For example, say it were a 2bd/1ba property, I would just list it for 1 nurse to stay and I would hit my cash flow goal.

Investors normally get there payments on time, most of the tenants stay for long periods of time because if they move it is a hassle for them, and since section 8 requires that the property stay in certain condition it will help keep the maintenance costs down. 

Even if you’re not an agent, staying connected with local agents can open doors.Exploring Older Landlords: This is something I’ve been doubling down on lately.

Does anyone know if there is any flexibility here, including if I can keep the HELOC if I have had it for 12 months (so stayed in the Primary Residence for a year after the HELOC started)?

I have personally stayed in one of these places where the main house is separated, and only the basement space which has a walkout entrance, its own kitchen, and two bathrooms would be rented out an Airbnb.

Sounds like if I stay conventional then my best rates will no doubt be the 25% down options. 

You don't want to lose your rate on the house you are living in now unless you want to sell it so since that is an owner-occupied, you need to stay there and save up the 20 percent for the second property based on what you said.

We stay +95% booked where folks may ask to rent a few days out vs months out on LTRs. 

Stay in and be part of this 721 or lose my investment most likely.

That's too much effort required to earn a few dollars on a short-term stay.
