Also don’t know your taxes there.  

Are there any central Texas builders out there that can offer me some guidance with these concerns? 

There is a great group of members on here to connect with.

It’s always been a good, affordable market overall, but you have to know the markets well, as there are good and bad areas for sure.  

Easy to use yourself too HELOC works (there may be some places that do a HELOCs on rental properties)I personally have used a 401k Loan on a few occasions - You're essentially borrowing money from your 401k and paying yourself back (interest goes back into your 401k as opposed to a bank) and if you don't pay your 401k back the loan would simply become a withdraw (maybe some tax penalties, but you could probably finagle a workaround).

Our land isn't in the middle of nowhere there are multiple residences surrounding and new construction projects happening right now.

Typically we do 25%BAC, but there are times we do incentives at 40%! 

If you want to offer a "rebate" of some kind after they stay up to date for certain amount of time, I'm more inclined to go that way, but in general theres no real good reason to put yourself as the owner in the middle of the utilities unless they aren't metered in a way to bill directly.  

There are a lot of people who bought during the pandemic that are now trying to get out.
