If he's just a bike enthusiast with tattoos and a job that doesn't mind how he looks, I think, if he can pay, he can stay.

I have a baby on the way with my beautiful wife and am laser focused on eventually replacing my earned income with cash-flow from real estate. 

The place is not without work needing done, but until December it had been rented by a tattoo studio (and a barber shop before that), and had a residential tenant upstairs for years. 

I can give laser measurements on the spot, as well.5.

Check the elevation of the corner and the middle to get the deflection of the good side then do the same to the spalled side (use a rotary laser, ground might not be flat).

Laser focus is key to any successful venture.

Be laser focused on your replacement and it's location well before you close your sale.  45 days will go in a flash. 

Quote from @LaDonna Davidson: You can deny them because you don't like their friends, for having a tear facial tattoo, color of their hair, etc.

Tattoo shop? 

What I see killing more exchanges than anything is lack of targeted focus.  45 days will go by in a blink if you're not lasered in on your target geography/sector prior to selling your property.
