Living for free is my primary goal right now, cash flowing on top of that is just a bonus. 

That was just after I bought my second house through them, and suddenly I'm getting a referral bonus when I buy my third now (I just entered escrow again).It turns out though that you can have roofstock add someone as your referral.

And the bonus depreciation on the new property(ies) could potentially offset your capital gain.

By investing in a commercial asset with highly accelerated (bonus) depreciation, you may be able to achieve losses that offset even more gains than a 1031-exchange can do.

Give yourself a window of time to accomplish any repairs required between residents.As an added bonus, when you pre-lease your home you have more time to screen and interview prospects instead of being rushed to make a last-minute, less-thoughtful decision.

You sign up with HUD and fill them with Section 8 tenants.

Both provide outstanding bonus depreciation and of course, the DST will also allow a 1031-exchange. 

The lifespan of each item is important because short lifespans let us do bonus appreciation.

You could either refinance your loan at that time to a Conventional loan to restore your VA entitlement for another property wherever you move to next, or without refinancing you will still have bonus entitlement to buy another property. 

Bonus!
