., but am now having difficulty finding actual cash buyers.

Degree of difficulty to police a forum is high.

What made it extra difficult is the fact that I wasn't able to sell my house first before purchasing this new house.

Or, if I didn't enjoy it.Changing tactics and strategy is par for the course with the rapid pace of societal and technological changes nowadays. 

It usually ends in failure or massive burnout or difficulties in having a life and family, etc.

Yes population has declined in Cleveland year over year (it has slowed considerably) and I know to many investors that’s an important factor, as it should be a consideration in the whole picture, however Cleveland as a whole is a huge city that still has a large population and an inventory shortage both to buy and rent so regardless of the population issue there will be no difficulty in renting units anytime soon.  

There should be no difficulty difference wether you buy a manufactured or single family home.

Then technology on my smart phone caught up with it and I no longer needed to lug around a two-pound, $1,500 piece of equipment.

@Dan Goeckel I do not use them for rentals as I had difficulty reaching them on a fraud claim a few years ago.

Just because my DTI doesn't fit the conventional lending criteria, doesn't mean I don't have the cash reserves to weather several months of difficulties.
