You got past the first big hurtle in real estate investment, signing up and reaching out in BiggerPockets.

Look for all spots where there is urine and spray this enzyme (Anti icky poo or Nature's Miracle).

Well I knew the floor was going to be bad after the horrible urine smell that was left in the unit.

The place was a mess, piled high with urine soaked trash, cobwebs everywhere. 

There is a product called OdorXit AQM which I used successfully in a unit which was very badly assaulted with pet urine. 

Once I gave up meeting people and looking at their cat urine reeking junk, I started buying a whole lot of stuff.

The entire house was covered in urine.

No matter what you would/could do with it you have three MASSIVE hurtles to jump over first. 1 - Historic Registry - This could put a lot of limits on what you do with the building.2 - Zoning/Re-zoning - More limits and very time consuming3 - Parking - If you don't have parking you can't put anything in here other than another church.

Animal urine is horrendous- I can’t stress that enough.

Dog crap , cat urine , rotten food trash , mold .
