Another option if you can raise a fairly significant downpayment (25-30%) and are entrepreneurial and can handle stress (!)

It saves both parties a lot of time and stress.

You can do the same with forced air but it's probably more difficult and expensive.I think you should wait for it to be a problem before stressing about it.

Difficult tenants can present a very stressful situation, especially if they've been a long time tenant and you're a new owner of the building.

There are a number of fine Real Estate trainers (my opinion) that you might also investigate that stress the client service aspect of business.

Stress to the people you speak with that communication, good, bad and timely is important.This is a very personal endeavor and you need to build your team around you to get your deal over the goal line.

Also having a job to pay the bills while you get your wholesaling business on track relieves a lot of stress.
