Early repayment will mean a 2% fee being assessed. 

Meanwhile this other guy has dozens of different shell businesses set up.

You have to be honest with yourself, understand the risks and assess if you can afford the negative cash flow.

I receive dozens of section 8 vouchers and deny most.

That includes going to the bank and getting a cashiers check.Pay them at the bank, get deed notarized there, then take it to Register of Deeds and file deed.I have done this a half dozen times to keep from missing out on a great deal.For what I'm paying any risk is negligible.  

@Brian Larson - Are you asking how to assess rental demand in any given market? 

Learn how to properly assess and QC the excavation and foundation phase, framing, roofing, siding, windows, etc.

As @Robin Smith mentioned, for assessing demand I used FurnishedFinder.com/stats; you can see demand data for a given city and some pricing data too.

A loose plan in hand is better than a dozen frantic Google searches, trust me.

There are dozens of real estate podcasts out there.
