In life we get caught off guard with Health issues, Death in the family, Loss of business or jobs (Unexpected pandemics!).

Some buyers (think Cary NC in the 1990s) are looking for attributes not related to economic value, like: common areas, access to public transportation, proximity to parks, etc.

I''m a health professional and my wife stays at home taking care of the kids The goal is to generate income and slowly retire from 9 to 5 job The house we live is paid off and we have 1 rental property which generates about $700 cash flow.

@Collin Brown, IRS Publication 523 addresses this quite nicely - Vacant land next to home. 

CO landlords can still evict for all of the common grounds for eviction: nonpayment of rent, violation of lease terms, damage to property, disturbing the peace, health and safety violations, illegal activities etc. and can also still evict if they plan to conduct repairs or renovations, property demo or conversion, move in to the unit themselves or have a family member move in, withdraw the property from the rental market, or if the tenant refuses to sign a new lease with reasonable terms. 

It sounds expensive, but perhaps the property falls under certain requirements, including interconnecting the detectors.Maybe this can shine some light:https://wbcapp.oaklandnet.com/cs/groups/public/documents/translateddocument/b3dk/mdaz/~edisp/dowd003911.pdf

Whether a property is listed publicly or privately doesn't automatically make it a bad/good deal, it just affects the visibility of the deal and more importantly: how motivated the seller is. 

Property tax is public record, you can look up a neighbor's property.Ask a neighbor about their utility costs.Call an insurance broker and get a quote based on your build specs.

Health, focus, will, and determination, along with a lot of other factors, will make Boomers want to exit.

You think he's in the public eye, and can't afford to screw people.
