As for capital, I will be utilizing my HELOC for initial fund on first deal.

One of the easier ways to do this would be to 1031 exchange into a DST where the sponsor owns a REIT and utilizes the 721 as part of their strategy.

After all PITI, utility, and services (lawncare and cleaning) costs I have $7,225.I set aside 25% of this for my maintenance fund.The remainder funds my lifestyle, wife has a Tesla, and quarterly vacations as well as business growth.In 2023 I am tracking to build 4 duplex units designed as room rentals funded in part from a recent land sale.

I have an incentive of $25,000 for going with the builder-specific lender, and I'm trying to figure out the best way to utilize it.

Quote from @David Randolph: Quote from @Minna Reid: I handle a ton of sales with HUD partial claims.

In addition to above, consider utility entrances.

However, if you're set on managing it yourself there's plenty of websites and apps you can utilize for rent collection.Some may or may not include messaging for requests such a repairs or maintenance, but if you're looking for rent collection there's quite a few options on the market that are affordable.

From the homes we manage here in Central Florida any benefit of your utility bill is negated by the financing of the panels.

I would especially if they are paying for their own utilities. 

Keep in mind that there may be legit charges associated with termination- for instance, they may need to hold some funds in escrow to cover lingering utility bills or cleaning after that 30 day period.
