I think it is more behind the demand for those units and your credit rating and your ability to pay the loan no matter what happens that counts.Your obligation is only the current leases and what law might apply in that city, that state, or the country it is located in. 

I was looking for an unsecured business line of credit and it led me to them.

Find the properties that are poorly managed and have rents below market.

My credit is fair and I don't have much cash on hand to finance this deal. 

I have a good credit score, family members with some money, $200,000 in stocks, bonds, and crypto, and i've started saving between half and two thirds of my income (which i can do because i live with my mom for free).

I have a good income, credit, and ready to do something.

Anyone in NJ interested in being a cash credit or needing someone to find that perfect deal let me know.

To me, poor tenants in "war zones" are too risky and A class properties have too little reward due to the low risk. 

If you have good credit you can get plenty of people to loan you money for rehabs.

As a rental investment it is not worth the risk or work load based on you having negative cash flow unless you are in a high appreciation market and willing to gamble.SFHs make for poor income property investments and are primarily a appreciation play.
