The big boys play this as a team sport, so think about what you need to know, who you can get it from and then go find that person.

A few things to keep in mind:Section 8 requires the property to pass an inspection based on HUD’s Housing Quality Standards (basically making sure it’s safe and well-maintained).The rent you charge has to align with Fair Market Rents (FMRs) in your area, so it’s good to check what similar properties are renting for.You’ll still be responsible for maintaining the property, but the upside is that a chunk of the rent is guaranteed by the government, which can provide steady income.Check with the local housing authority about any specifics for your area—every jurisdiction does things a little differently.This could be a great niche if you can find a good deal on the land and make sure your expenses (like maintenance, insurance, and occasional vacancies) are covered by the rental income.

Renewals and rent increases- Research market rates; 3% is fair, but adjust if you’re far below market.

This agent of your didn't play any part in finding this property for you.

All you get is what you can export/import via CSV file:(We use Propertyware, have experience with Buildium, and have played with Appfolio and RentManager.Buildium is for smaller companies.The other three are tied, the differences being how much automation & customization you want to do.If you don't see yourself growing beyond 150 units, go with Buildium.If you're not very techy and plan to grow over 150 units, we'd recommend Appfolio.If you're techy and plan to grow over 150 units, we'd recommend Propertyware or RentManager.Of course, schedule some demos, take GREAT notes and them make your decision.FYI - there are MANY new options on the market, RentRedi, TenantCloud, Apartments.com, Hemlane, Rentec.

All of my assumptions were based on that 2 unit residential and are fairly accurate between rental rate and ARV. 

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

I dont believe there is any kind of HOA or ruling organization for these group of houses but it has me concerned that if one day they all decide they want to repave the driveway or add lighting or something along those lines, they would try and make everyone chip in and pay their fair share. 

Unit is available now -- just publish that and let the rest play out?
