Whatever $$$ value gives you security against the potential damages (stained carpet, chewing on anything that's wood, even some people who let the dog urinate and defecate all over the house).

My only hurtle is the cost for the IDX and/or any other services other than hosting that i'll need in regards of running a real estate agent site.

I pulled some of the smelliest pet urine smelly carpet out of another unit this week.

It took a month to clear the smell (she also had two dogs and two cats who urinated indoors) with fans, filters, repainted surfaces, stripped and resurfaced floor, and more.  

You might be able to get a judgement for late fees but do you know how hard it is to remove the smell of cat urine?

If you do not mind taking the risk of extensive property damage, flee infestations, difficulty re-renting due to urine smell and every other possible problem then you are right.

Since this process I have asked him if he would take half the funds cash and the other half in payments, and he just is not interested, when i had to jump over some hurtles in the process until underwriting rejected the property.

Cops have also been inside the house and have witnessed signs of extremely unsanitary conditions: pet waste/urine around the house, you get the picture..

The tiles cannot be repaired or replaced so the entire room of tile needs to be replaced at a cost of over $7700.Also the tenant's cat damaged the finished basement so severely with urine that not only did the carpet and pad need to be removed, but also the baseboards, lower 2 ft of drywall and in one area the insulation.
