The risk is a mouse infestation in late Fall. 

Thank you Get the entire house treated and have the pest removal company write something up stating where the infestation came from (downstairs unit) then bill the downstairs tenants for the entire cost of pest control.

When I had a mouse infestation behind the walls with heavy mouse urine smell, I hired a cleaning pro who had a professional thermal fogger who used steri-fab/ sporocidin and eliminated the smell.

After 25 years of dealing with root infested old clay pipes & renting the roto-rooter 2xyear the city tore up the street to replace the sewer lines.

Dead body, overdose, tenants fooling around with other tenants spouses, break ins, walking in on an intruder (2x), pet rattlesnakes that escape, water leaks, broken air conditioning, flea infestations and people trying to rip you off. 

They blame tenants for sewers clogging when the sewers are infested with tree roots.

The units appear to be infested with mice. 

But the effect is most pronounced in the tech hub of San Francisco, where companies are 1) more likely to implement “work from anywhere” policies or 2) have shed jobs as the pandemic crushed their business.I've heard horror stories about Real Estate Prices in the Bay Area, but do you think this could bleed into the San Antonio market since so many Californian's are "infesting" Texas? 

Brokers may not even present your future offers to their sellers.Brokers will be a bit more forgiving if there are things you could not have known from a property tour (e.g. it has a termite infestation) or things the owner was hiding from you (e.g. they didn't show you the unit that was gutted to the studs). 

The previous one did not keep the house clean and I had to deal with roach infestation.
