Anyone that's been doing this since before the recession operated in that world, I have not and don't think I'd have been a good fit for that world.I know a few realtors that gave up on lending and became realtors specifically because they could not be competitive in a world that rewards crummy behavior.

@John Suralik  subject too is a very old and easy method of acquiring RE its not big deal. what it is is uber risky for sellers unless the sellers have already lost their credit and don't care and are walking.. the reason is you take Title subject too  the existing loan.. remember loans stay in place unless paid off and even though all debt instruments have alienation clauses they are rarely envoked.

I suggest checking the building history to see if there are any existing violations that you'd have to clear up and if there's any civil penalties involved.

There are lots of great opportunities in Real Estate along with rewarding work that's involved.

Which means you cannot keep your existing loans in place.

zipcodes to consider.....21239, 21213, 21206.....good and bad exist in each of those, one must know the neighborhoods, streets, and blocks to accurately determine good vs bad.

Are you putting a non-existent down payment in to get your IRR and other metrics?

Personally, citing numbers to a buyer, your current economics is not the issue.You site the Purchase Price, assume an LTV and calc the loan payment for say 20yr, 4.125%.Calc the existing GSI, expenses (with new taxes, insurance) but sans the principle and interese, and derive the NOINow you've got the data for cash/cash and cap rate.These numbers should entice the buyer to be interested BECAUSE there's a cash flow and/or cap rate.
