It probably will help if you can partner with someone with some gray hair, and even if that just means you'll be borrowing their name/credibility at first, that's one way to overcome the "age" hurdle. 

In terms of FHA, just as Dave said, try to avoid them, but sometimes they’re the best/only option.While you can go through your typical, every day bank, I would strongly recommend seeking out a credible, local lender.

AirBNB does not allow you to set a minimum age BUT - in their "you have an inquiry" email they'll tell you if the person is over/under 25 (right next to saying they have verified government ID).  

Penetration pricing - get traction with early bookings at low prices, gain credibility with 5 star reviews, and improve pricing / profitability from there.5.

As I mentioned before, it's all about personal preference, so that should be your (and other's) foundational guide.One anecdote: The most successful real estate investor I know, personally, invests in a great number of government and university treasuries. 

Purchase price: $150,000 Cash invested: $80,000 Single Family Home in a nice area (Close to DC, in MD; Blue Collar & Government Workers).

Probably has a bigger impact on government programs and the need to extend social security. 

Sadly, many people, including those in government, are oblivious to what landlords like us do for tenants.

The $40 application fee goes towards tenants' first month's rent. 4) Along with the application, provide me with an employer reference I can call for income verification, previous landlord reference, a copy of their last 2 pay stubs or form of monthly income, a copy of their last W-2, and a copy of some form of government issued ID for everyone in the household.I know this is a lot, but I'm not sure what I could take out to make this application process more appealing.

From my understanding the government pays a portion of their voucher and the tenant pays the rest.
