In today's competitive real estate market, having modern amenities can set your property apart, making it more attractive to a wider audience.

The investment portion of 3 units equals their reinvestment target of $600K. 

Its good that you've already established some target markets, I'd recommend diving deep into 1 or 2 markets, then branching out. 

Target Price: $575K-$589K; ARV: $630K.

Personally, I like to target 30% equity retention in each deal.- Section 8 income isn't guaranteed.

if anything then I would set a flat fee to pay them for their service and then if you do find a property that offers buyers agents money, in which almost all I have seen still do...then I would have the title company back out the amount you decided on and the agent gets the remainder of the amount of commission that's left over. 

Now you repeat that process until it's paid off.Disadvantages:It took a while for me to set up.Bank account is always low, lol.People can spend a lot with that amount of credit.People think I'm weird when I tell them DId you analyze what would happen if you moved all of that money you were using to pay off a heloc, not get a heloc and put that money in a treasury or other type of account that got you 6% interest or invest in an ETF or something lower risk?

However, a lot of concerns can be mitigated with looking at their past rental behavior in a lot of different settings.

We believe that you set your strategy early on during acquisition, and as such, were primarily motivated by cash-on-cash returns and the strategy, with all of its pitfalls, did result in very reasonable IRR over the many years we have held.   

First thing I recommend is to figure out your target market.
