Both platforms push high volume, low price models because that is in their best interest.

I have done around 50 deals, but only 5 with this model.

I was envisioning a two part calculation for the monthly mortgage payment - I see it as a VA loan analogy with no money down but the loan structured with two interest rates (one for the TSP down payment and one for the 30 yr fixed rate mortgage).I guess the real question to ask myself (using your situation as the model, assuming positive cash flow once TSP is repaid) is whether I am okay tolerating the potential 60 months of negative cash flow to get to the positive cash flow after 5 years.- Maybe if it gets the deal going and leads to a cash out refinance before the 5 year mark that allows me to speed up the TSP pay off.Wow - Great food for thought. 

Your business model cannot be sustained. 

I'm using my latest acquisition, the Tampa property, as a model for my new investments. 

Are their prices clearly advertised on their website or is the model "it depends" which is always a red flag.

Or if you buy a duplex, live in one side, and work the deal so the tenant is paying all or most of the mortgage (some circumstance like that).Buying a rental house (or 20) the right way, and renting them out forever is one of the best passive business models I’ve ever experienced.

When we get awkward 2-3 week gaps and have to switch to an STR model, it's a PITA because we're cleaning ourselves.

I know how to build models, I know the lending process, and I'm an excel junkie.

It's a scalable model if you have a solid team built out to help you manage scheduling and checking out.
