I have a large MF lot I am looking to put a modular pre-fab or panelized 5-10 unit building on due to lack of available labor...builders are all busy.

Average apartment rent of $1070 to national $1470 (25% delta to the downside, in one of the highest growth environments in the nation)3.

As some other mentioned there are a good handful of questions to ask such as how they screen tenants, lease units, fee structure and try and ask for references on some of there older clients as well as newer ones as well.

Obviously I plan on increasing his rent to market value and switching utilities but hesitate increasing it past 20% due to the fact that during our walkthrough he seems like a solid tenant with a very well kept unit and even bought his own washer and dryers in the unit. 

Appfolio has an option for the daily late fee charge, but they do require a minimum of 50 units to use the software.I would check to see if Buildium offers this option.

No pool needed.As a frequent mountains traveler I will not consider a unit with no view and no hot tub.I am not experienced in Charleston, but from what I know these would be extras and probably not essential for renting. 

I've seen a few 5-8 units for sale around there over the last nine months for my price range.

I converted my garage to an ADU and now my main house is considered RSO unit since it was built before 1978.

I good way I have found to generate leads is to call the Section 8 reps' to let them know that you have a unit that you're looking to fill and see if they have any clients who have a voucher that match your property. 

Big enough to have a national foot print usually means some economy of scale price wise.
