Every house has it somewhere and generally when it happens it is the tenants fault.. or in the case of Ohio basements are basically never ever dry. 

The first 5 times will be painful and frustrating - watch one of Brandon's or David G's videos on how to run the numbers - you'll become quick after a few dry runs.Just make sure you underwrite the deals against your Goals (ROI %, Cashflow $, potential longterm appreciation, etc), and run the numbers as if you're NOT in the property. 

I say that because the primer to cover the water stain may have to have your renters And their pets out of the unit for so many hours while they do it and then it dries because it may gas off.

I would give similar advice to someone that wanted to open a restaurant, landscaping company, hair saloon, etc.  

In CA, landlords provide microwave, ove, dish-washer, washing/drying machine and gardening.Let me know what you think.

Economic downturns can be very destructive and jobs can dry up.

In both cases, the tenant should be educated on their responsibilities and held accountable.Even if the water source were a leaking pipe or roof, you should be able to identify the problem, dry it out, and remove the mold professionally within a few days and then the problem goes away.Simply accepting the tenant's claim - without verification - and allowing them to break the lease without penalty is a bad policy that will cost you much more in the long run.

You don't sell refrigerators to Eskimos, hair curlers to Nigerians, or rentals in a market with no renters.2. 

Communication, honesty, transparency, humility, and a good head of hair.

@Gregory Jerome It’s no longer legal to do a “dry” closing.....no funds from the B buyer, using the C buyer’s money to first the AB transaction, then the BC transaction.
