The houses are wired up into the power lines and tenants buy their water and collect it in these giant rain buckets.

Water/sewer looks very high.

Does this muddy the waters when retirement age comes?

: conventional 30yr loanOther notes:- Our COC estimates are about 12.5% with us managing the property (vacancy and maintenance factored in) - Has older water heater, HVAC, and AC unit that have been regularly serviced, but are higher on ageQuestions- Should I be worried about an economic downturn on a buy and hold property next to a college campus and generally economically stable area?

Sheds water, keeps sun heat out of the unit and it's a one time deal.

How will utilities keep water and power up when people can't work together in offices? 

What I'm looking to do is detect water in common areas such as under the hot water tank, sinks, and such locations.

My capex budget includes roof 25 year life span( flat roof only 15), floors 10 year life span, appliances and hot water heater 12 year life span, hvac 20 year lifespan, bath and kitchen remodel 20 year life span, etc.

Recently,  numerous property listings I have walked in 5 points have either significant foundation issues or lots of standing water in the crawl space (one property we could not even get into the crawl space because of how deep the water was at the crawl space entrance!).  

Then add to that: don't shake their hands, wash your hands with soap and water more frequently, if the place they are viewing is unoccupied, open the door and then let them view it while you wait outside, answer any of their questions outside (in the fresh air).As for tenants, don't send anything out.
