And now they use AirBnB to find revenue enhancing opportunities.My FIL got popped for a decades old carport, he insisted on reconstructing it...

In Sisters last March there were 16 pending this March there were 22 pending.  

They repeatedly insisted I reduce my DTI but hopefully they get what they need to move forward soon. 

Additionally, if the prospective tenant insists on applying knowing that the building is not approved, let them know an estimated timetable of how long the inspection/repair/re-inspection process will take and that there is no guarantee - it may take longer.

If she insists on a penalty for breaking the lease make sure you insist on proper notice when she comes over, including mowing the lawn.

If you want the driveway, INSIST on paying, but ask him to do it for ridiculously cheap ($50 + some booze) and get an invoice, and a receipt just like you normally would.If they agree to that, you should probably be ok.

I also want to add, in case you insist on replacing them, the round-front toilets (circle bowls) are generally in older homes (although still available) and you may be more inclined to replace those or atleast inspect them closer.

I've countered and agreed to his low number for a 1 year lease and he still insists on a 2 year lease with option to renew.

I will let them come to an open house if they insist but I won't set up an individual showing. 

If anything could get further damaged you may wish to insist they get rid of th ecat.
