You can put the cash towards your next property, and/or unanticipated expenses with your current property, and/or changes in the economic climate. 

I feel the investment climate has changed radically since my last post and wanted to get some advice on the safest places (diversification, I believe, is key) to park the remaining cash that would generate enough passive income to semi-retire (these recent deaths have left me emotionally and physically exhausted and I feel I need a year or two to recover on a beach somewhere).

We have all the business advantages, constricted building will drive appreciation, pool of tech workers moving from CA, and a more mild climate. 

See rule 1  When Zillow, Opendoor , MF syndicators and Homebuilders are having difficulty making money in the current business climate, why do you want to force yourself to invest in a sector in which you do not even have experience ..Rather than losing money, better put that money somewhere else.

Not the best climate to invest IMHO.

Davenport has a growing population due to it's business friendly climate and has a diverse economy which is something I always look for when evaluating a market.

We have had to complete two evictions due to non-payment, we didn't renew a tenant due to their lack of cleanliness inside and outside the unit (along with other issues), and have had one tenant that never ran the A/C or opened windows in our tropical climate, which caused issues with mold and mildew throughout the unit.

*Provide adequate climate control in order to keep moisture levels down and prevent mold growth by opening windows or using a dehumidifier if necessary.

If you feel like you're being mean, then lookup some resources for homeless or displaced women in your area and provide that resource to her and tell her you empathize with her.I don't know this persons story but it could be anything from true, to having personal life drama that you dont want in your rental, there could be illegal activities/drug use involved (pressured speech, confabulation of wild stories) or perhaps just unfortunate uncontrolled mental health disorder.
