This clause is referencing surface mold which is generally due to window condensation or failure to ventilate in bathrooms and not properly cleaning surfaces.

The association replaced some lights and siding and did a back deck repair on them while I owned it, but I ended-up replacing a bad garage door and air conditioning condenser because those items were not covered.With an HOA, your fee is supposed to go to ongoing maintenance and some larger replacement items, BUT.... if the HOA is bad at managing their money and/or they have a bad balance sheet you could and likely will get stuck with the bill as a special assessment for your portion of that capex item.

Seller hired a technician, and he supposedly replaced the filter, charged freon, cleaned outside condenser coil, and "serviced" the HVAC unit.   

Executive SummaryThis Executive Summary section presents a condensed description of the investment.

Flip side, had a home warranty paid as part of a seller concession and first day we got access (in July in Texas) AC flooded the bedroom with condensate.

I do expect some capital expenses in the next 5 years like the A/C outdoor condenser unit and roof. 

You must ventilate otherwise you will condensate water vapors in this space. 

One of the things he noticed is that there is no drain pipe next to the condenser unit (like there normally is); there is no visible drain pipe anywhere. 

Think of what happens when you pour a cold beer in a glass on a hot day - you get condensation.
