I had 3 interested buyer.

If all else fails, 😀 ReSure's got extensive resources on all these subjects in our educational platform (which actually includes some plagiarizing from Michael!

We also learned that the house had failed or not received many of Baltimore city’s permits and inspections.

@Cheryl J McGrath  Personally I don't see why any RTO buyer would enter into an agreement  and put down money if you don't own the house yet. 

However, there is a mortgage on it with about 80k left, is it even worth trying to still go for this house or is that up to my buyers to see if they would want it still?

We have a tons of lots around here like the one you described, many of which can be bought for cheap and are not listed because there are just barely any buyers for such.

If all else fails, you have options to travel abroad and work in one of their office in any of the 80 countries where they do business!

Quote from @Chas Lumley: Quote from @Caleb Brown: Getting leases is typically done once under contract, I always have verbiage that leases will be reviewed by buyer within the inspection contingency.

Should be good and very popular with buyers once we get to the Spring market.

Take for example, while representing buyers in single family transactions, during the negotiation, I ALWAYS ask the sellers to credit the buyer(s) up to 3% of the asking price toward the buyers costs.
