What Does This Actually Cost Per Month?
Your parent could be in their own home for around $1,200/month — financed. That's less than most Jacksonville assisted living facilities charge per week.
How Most Families Pay for It
HELOC (Home Equity Line of Credit)
If you have equity in your home, a HELOC is often the fastest and lowest-cost path. You borrow against what you already own — no need to sell or refinance. Many Jacksonville homeowners qualify for enough to cover an ADU build outright.
Construction Loan
A short-term loan that funds the build in draws as work progresses. Once the ADU is complete, it typically converts to a standard mortgage or is paid off. Good option if you don't have significant home equity yet.
Cash from Parent's Home Sale
This is the most common path for families we work with. When a parent sells their home, those proceeds fund a permanent ADU on your property. A $140K–$180K build once compares very favorably to $4,000–$6,000/month in assisted living over 5–10 years.
Local Lender Connections
We work with Jacksonville-area lenders who are familiar with ADU projects and understand how to appraise them correctly. We'll make the introduction — you talk directly with the lender, no middleman fees.
The Real Numbers
A $140,000 ADU financed over 15 years at ~7% interest works out to roughly $1,258/month. Once the loan is paid off, your property is worth more and your parent has a permanent home — not a month-to-month lease.
Compare that to Jacksonville assisted living: $4,000–$6,000/month, every month, indefinitely — with no equity, no ownership, and no guarantee of availability.

Common Questions
Can I use my parent's home sale proceeds?
Yes — and it's the most common path. When a parent sells their home, those funds can go directly toward construction on your property. We'll walk you through how to structure it on a free call.
Do lenders count potential rental income?
Some do. If the ADU will be rented, certain lenders will count projected rental income toward your qualifying income. This can increase how much you're eligible to borrow.
Does adding an ADU increase my property taxes?
Adding a permitted structure will increase your assessed value — but the increase is typically modest relative to the value added. We recommend speaking with a local tax advisor for specifics.
Can I rent the ADU to cover the payment?
In most Jacksonville-area jurisdictions, yes. A 1-bedroom ADU in Jacksonville typically rents for $1,200–$1,500/month — which can fully cover or offset your monthly loan payment. Check your county's rules on our Eligibility & Cost page.
