I've been playing with amortization calculators and have seen you can pay off 1/3 of the mortgage and reduce 2/3 of the duration.

Also, its much cheaper to send a larger volume of street view postcards or letters using a large printing company than it is to send through deal machine.

But if they wanted less control in investments---go the route of equities, fixed income like tbills or CDs, mortgage notes syndicators, REITs, possibly RE syndicators but do your diligence especially now, and even crypto cause that's an investment with little control.

Our go to lender to @Jose Valdovinos with Cross Country Mortgage...I am almost certain that they can do loans in the ATL, but hose can confirm. 

It'll add about 80k to the cost but is a much cheaper option that tying up square footage for an indoor pool and dealing with the risk of moisture and mold issues.

Let’s be conservative and say that it would only sell for $300k : you spent $100k on it anyway… and now your over all mortgage would go from $700k to minus $300k or $400k.

Are you taking this subject to existing mortgage?

Maybe it can be a little cheaper on subsequent deals, if you aren't changing much.Loan apps: while you may be able to have some investor money funded before this is due, you may not.  

I have a mortgage connected that, for some reason, reports it as an escrow balance, throwing off my balance sheet. 

FHA has a lot more paperwork, up-front PMI, plus you have monthly PMI for the duration of the mortgage.
