Then I heard about Quickbooks Online.

@Cameron Belknap FHA loan rules in HUD 4000.1 mention not counting the basement as part of the Gross Living Area; however, part of the FHA requirements found in HUD 4000.1 includes a section on “converted spaces” which states:“The Appraiser must treat room additions and garage conversions as part of the GLA of the dwelling, provided that the addition or conversion space…is accessible from the interior of the main dwelling in a functional manner; has a permanent and sufficient heat source… and was built in keeping with the design, appeal, and quality of construction of the main dwelling.”Furthermore,“The Appraiser must analyze and report differences in functional utility when selecting comparable properties of similar total GLA that do not include converted living space.

Other things you need to factor in: utilities like satellite TV/internet (which, since the house probably doesn't have access to cable, internet can be An Issue), and will the HOAs allow short-term rentals?  

You need to find leads where no one has access to them.

There are so many great free educational resources online on the details of flipping (and saving on taxes), and even more on straightforward rentals.

Some are 100% commission with monthly fees, agent transaction fees, and a website and full access to CRM.

The other structure that came long in 2004 in response to wall street wanting a product to access 1031 money was blessed as the Delaware Statutory trust.  

The most important thing you can do is to hook up with investors in your area to learn your local laws, closing attorneys (or title companies), how to buy, investors you can sell the wholesale deals to, etc.Reading online is a great back up, but you must connect locally.

Plenty of samples online; tailor to your transaction.

In short, an allotment that gets subtracted from the paycheck before the service member has access to it.
