Already called the police and they successfully removed him and I secured the property but im concerned that he keeps showing up when the unit is ready to resale/rent. 

Typically there are about 20 units listed for rent at any given time on the MLS over the last 5 years or so.

You can do this on a 30 year fixed mortgage if they are 1-4 Units at a low 7 percent interest rate as long as the property debt services over 1.00 and FICO is 720+

So I recently bought a triplex at 20% down and I live in one of the three units.

Here is the situation: I purchased a 3-unit multi-family property in Elizabeth Port 7 months ago.

I have a tenant that wants to move into one of my other units right away on the first.I am trying to accommodate them the best way I can by doing my final walk through inspection of the place at the end of the month when the Tennant leaves (notate repairs and habitation of unit) and complete a new walk through with the tenant moving in.Tenant is begging to have their cleaners come in the morning of the 1st which interferes with the walk through.

@David RosenthalI have about 9 units rented with section 8 in Columbus.

I have rehabbed about 2 dozen units which I consider a fair amount of experience.  

Hi - any commercial appraisers out there or someone in a similar scenario of buying a multifamily with one nonconforming unit?

Yes, I've reported to bad check unit, but not sure that there's going to be any success in getting money back from that.
