People come to us with renovation questions from a lot of different directions. Some are homeowners who want to remodel a kitchen, add a bedroom, or build an ADU in the backyard. Some are buyers who found a home they love, but it needs work, and they want to finance the purchase and the renovation together. Some are investors who buy distressed properties, fix them up, and either sell or rent them.
All of them run into the same problem: the financing options are confusing, and most lenders either don’t explain them well or only know one or two of them.
We specialize in renovation financing. It’s one of the things we do best, and it’s become a significant part of our business because we take the time to understand which option is actually right for the specific situation – not just which one is easiest to process.
This guide walks through every option available. Read the section that applies to you, or read all of it – either way, by the end you’ll know what fits your situation and what the path forward looks like.
Already own your home
The HELOC — your equity as a flexible renovation tool
If you own a home and have built equity, a Home Equity Line of Credit – a HELOC – is often the simplest way to finance a renovation.
What a HELOC is.
A HELOC is a revolving line of credit secured by your home’s equity. Think of it like a credit card with your house as collateral, but at a much lower interest rate. You borrow what you need, when you need it, during a draw period that typically runs 5-10 years. During that time you often pay interest only on what you’ve actually drawn. After that comes a repayment period of 10-20 years where you pay principal and interest.
How much can you borrow?
Lenders typically allow you to borrow up to 80-85% of your home’s current value, minus what you still owe on your mortgage. So if your home is worth $400,000 and you owe $250,000, you might be able to access up to $90,000-$100,000 in a HELOC, depending on the lender.
When a HELOC works best.
The limitation to know: a standard HELOC is based on your home’s current value, not what it will be worth after the renovation. If your equity is limited today, the HELOC may not give you enough to fund a major project. That’s where the next option comes in.
When your equity isn’t enough — the Renovation HELOC
For major renovations – a full kitchen gut, a second-story addition, an ADU in the backyard – you might need more than your current equity allows. That’s the problem the Renovation HELOC solves.
The key difference: after-improved value.
Instead of calculating your borrowing limit based on what your home is worth today, a Renovation HELOC uses the appraised value of your home after the renovations are complete – called the “after-improved value” or “as-completed value.”
A simple example: your home is worth $350,000 today, and you owe $200,000. A standard HELOC might give you $80,000-$100,000. But if the renovation you’re planning – an addition, a kitchen overhaul, an ADU – will push the value to $500,000 when it’s done, a Renovation HELOC could give you access to significantly more. You’re borrowing against what the home will be worth, not what it is worth.
What you need to qualify.
The lender will require detailed contractor plans and cost estimates so the appraiser can value the completed project. You’ll need good credit and sufficient income to support the payments. The process is a bit more involved than a standard HELOC, but for larger projects it can make the difference between a renovation that’s possible and one that isn’t.
Good fits for a Renovation HELOC.
FHA 203k — for buyers who need flexibility
The FHA 203k is government-backed, which means more lenient credit requirements and a lower down payment – as low as 3.5% with a 620+ credit score. It comes in two versions:
Renovation must start within 30 days of closing and be completed within 9 months for a Limited 203k or 12 months for a Standard 203k (extended under FHA’s 2024 program updates). You can borrow up to 110% of the after-improved value.
Fannie Mae HomeStyle — for buyers who want conventional financing
HomeStyle is a conventional renovation loan – no FHA mortgage insurance structure, and it works for primary residences, second homes, and investment properties (with higher down payment requirements for non-primary). Down payment starts at 3-5% for owner-occupants. You can finance up to 75% of the as-completed appraised value in renovation costs.
HomeStyle allows almost any type of renovation – structural, luxury improvements like pools, ADU construction, even outdoor kitchens. The renovation must be completed within 15 months of closing. If the home is uninhabitable during renovation, Fannie Mae allows you to finance up to 6 months of mortgage payments into the loan.
Which one is right for you? If your credit is strong and you want more renovation flexibility, HomeStyle is usually the better product. If you want a lower down payment or have a credit score in the 580-620 range, the 203k may be your path. We’ll help you figure out which one fits your situation.
For veterans
The VA Renovation Loan — an option most veterans don’t know exists
This one is specifically for veterans and active-duty service members using their VA home loan benefit. Most people know VA loans offer zero down payment and no private mortgage insurance. What most people don’t know is that there’s a VA Renovation Loan – sometimes called the VA Rehab Loan – that allows you to purchase a home and include up to $50,000 in renovation funds in the same loan.
Why this matters.
Standard VA loans have a Minimum Property Requirements (MPR) standard – the home has to meet certain safety and livability standards before the VA will guarantee the loan. That puts a lot of fixer-uppers that would be great buys for a veteran off the table under a traditional VA loan. The VA Renovation Loan changes that: it allows you to purchase a home that doesn’t yet meet VA’s standards and use the renovation funds to bring it up to those standards and beyond – a new roof, updated electrical, a functioning HVAC system, or general repairs to make it safe and livable.
How it works.
We believe veterans deserve to use every benefit they’ve earned. If you’ve been passing on fixer-upper properties because you assumed your VA loan wouldn’t cover them, there’s a real chance the home you want is more attainable than you think.
For investors
The no-doc investor renovation loan — buy it rough, fix it up, sell or hold
If you’re an investor – or thinking about becoming one – and you want to buy a distressed property, renovate it, and either sell it for a profit or hold it as a rental, the programs above aren’t designed for you. The no-doc investor renovation loan is.
What makes this product different.
Who this is for.
What to know before you pursue this.
This is not a long-term hold product – it’s a bridge. You buy, renovate, and exit. Rates are higher than conventional investment property loans because the risk profile is different, and there is typically a prepayment penalty period. Down payment requirements vary by lender and project – as a general planning figure, expect to put roughly 20% down on the purchase price and 20% toward the renovation budget. Some investors take a different route to the same result: buy the property with cash or a home equity line against their current residence, complete the renovation, and refinance afterward once the improved value is in place. The strategy works best when the math on the deal is solid before you start – we can help you analyze whether a specific property makes sense for this approach before you make an offer.
ADUs and additions — financing a project that doesn’t exist yet
Adding an accessory dwelling unit – an ADU – or a major addition to your existing home is one of the most financially powerful things a homeowner can do right now: more space for a growing family, housing for aging parents or adult children, rental income, long-term property value. The financing question is a little different for these projects because you’re not buying a new home – you’re building something new on a property you already own.
The HELOC or Renovation HELOC path.
If you have meaningful equity in your current home, a HELOC or Renovation HELOC can fund the construction. A Renovation HELOC based on the after-improved value is particularly powerful here – if adding an ADU will push your property value up significantly, you may be able to access more financing than your current equity would suggest.
The Fannie Mae HomeStyle path.
HomeStyle explicitly allows ADU construction and room additions. If you’re doing a cash-out refinance of your existing mortgage and wrapping the renovation costs in, HomeStyle can work – especially if your current mortgage rate is similar to today’s rates, or if you need more borrowing capacity than a HELOC provides.
The FHA 203k path.
The Standard 203k allows for additions and structural work on a primary residence. If you’re refinancing an existing FHA loan or your credit profile fits FHA guidelines, this can be an option. The 203k consultant oversight requirement adds some process but also provides structure for complex projects.
These projects require permits, architectural drawings, and licensed contractors, which means there’s more planning involved before financing can be finalized. The earlier you bring us into the conversation, the better we can help you structure the financing around the project timeline. Susan also co-owns Curated ADU Homes, which helps homeowners navigate zoning, the approval process, and builder selection for ADU and intergenerational-living projects – ask us about it if that’s part of what you’re planning.
How the process works, start to finish
One of the reasons renovation financing intimidates people is that it seems more complicated than a regular mortgage. It is a little more involved, but once you understand the process, it makes sense. Here’s how a renovation purchase loan typically works from beginning to end.
01
Find the property and plan the renovation.
Before we can complete an approval, we need to know what you want to do to the home. Get contractor bids and a scope of work for the project – the more detailed, the better.
02
Get pre-approved.
We review your income, credit, and assets, and we look at the property and the renovation costs together. We’ll tell you which loan product fits and what the numbers look like – purchase price plus renovation costs, single loan, one payment.
03
The appraisal.
An appraiser evaluates the property based on what it will be worth after the renovation – not what it’s worth in its current condition. This after-improved value determines your maximum loan amount.
04
Close on the loan.
At closing, funds are allocated to the seller for the purchase, and the renovation funds go into an escrow account managed by the lender.
05
The renovation begins.
Your contractor starts work. Renovation must begin within the timeframe required by your loan type (30 days for 203k; no specific requirement for HomeStyle, but within the 15-month window). Work is completed in phases.
06
Draw requests.
As work is completed, the contractor submits draw requests and an inspector verifies the work before funds are released. This protects both you and the lender.
07
Final inspection and completion.
When all work is done, a final inspection confirms completion. The renovation escrow closes out and you’re left with one mortgage on your newly renovated home.
Repairs and renovations also cost more than they used to, so budget for that rather than being surprised by it. The bigger piece is having contractors you trust – people who do good work at a fair price, and a relationship you maintain rather than a one-time transaction. A simple system that works well: once a year, walk the property (or have your contractor do it) and put together a list of maintenance items, so ongoing repairs happen on a schedule instead of as a series of emergencies. Long-term, plan for the big-ticket items too – roofs typically need replacing every 20 years or so, HVAC systems every 15-20, water heaters every 10-12. None of that is a surprise if you planned for it.
Which option is right for you?
Start here: are you buying a new property or working with one you already own?
