Hi Michael,A reason why the square footage may not have been included is if was not "finished". unfinished areas or attics, or areas only accessible through unfinished areas will not typically be included in the square footage.

Definitely looking forward to accessing his services.  

That said, I would also consider beach towns that are out of state but with easy access (ie. a short flight.. say 1-2hrs).

Thousand Oaks, Stone Oak, Encino Park, Bulverde, etc)- Schertz/Cibilo (not far from military bases, easy access to Austin/New Braunfels, up and coming/ many new nice neighborhoods)$250-325K RangeNorthwest - (Near UTSA, Medical Center, Shavano Park, Rim)$200-275K Price RangeFar West - Castroville, Alamo Ranch, Sea World Area

They are public records, but that doesn't necessarily mean they're easy to access.

I do believe this venue will give me greater access to people and tools.  

However, this requires careful legal handling.Other options:Reverse Mortgage: If your parents are over 62 and the home is their primary residence, a reverse mortgage might be an option to access equity without monthly payments.Home Equity Loan or HELOC: If you have significant equity, consider a home equity loan or HELOC to cover your parents’ rental expenses, then repay it over time.The Good: Co-ownership can provide financial relief and shared responsibilities.

If it's a vinyl window, or if you could swap out the existing window for a vinyl window without much hassle (e.g. if it's on the first floor and you have easy access to the exterior), then waterproofing the inside shower area around the window would be much easier.  

Did they also have access to the yard where you are building the ADUs?

You may need permits for plumbing, electrical, and structural changes.A HELOC can be a flexible and cost-effective way to access funds for a down payment on another property.
