I know this is pretty obvious, but have you tried checking the Montgomery County property tax records or the property tax assessment records online for Silver Spring?

The house probably also has delinquent taxes etc on it as well.

Also, during those 2-3 years you may have to bear to obtain possession, the borrower will probably ignore court orders to pay insurance and property taxes, leaving you out of pocket for those costs.  

so most people will have to be as leveraged as possible to scale (at the beginning). as in, keep your LTV high and focus on buying 'as much' ($$) RE as possible. this is if you're doing a pretty run of the mill REI strategy like buy and hold. i came across an interesting guideline once: if you could sell today and net 7x+ your annual true net cashflow, you should cash-out/refi, or sell/1031. think of it this way: if your portfolio in a year is worth 1m market value, and you owe 600k, and have a lender that will do a portfolio loan at 80% ltv, you could cashout refi and get 200k to play with (minus closing costs). when you compare the now-lower cashflow from the existing portfolio (higher LTV & maybe different rate), to what you can do with 200k cash, THAT'S where it gets fun. maybe you lose 1k/mo in cashflow on the original portfolio (literally just made up a number, idk), but you can gain 2500/mo in cashflow with that 200k.. then doing the cashout/refi earned you a net increase in your monthly profit of 1500/mo, plus you're getting debt paydown and appreciation on "more" real estate, probably getting bigger tax benefits, etc.

Could use some guidance on how to divide the business, taxes, and payouts.
