If it is zoned for a duplex or AUD (Accessory  Dwelling Unit, i.e. mother-in-law unit) You will have to get Permits and bring it up to todays codes.  

Being a little under also helps you keep your turnover low which is the mother of all evils for any landlord.

My mother makes her living managing several of her own properties, however, I decided to go with a property manager because I didn't want to add to her load AND it would be a good drive for her to get to my property.

When she hadn't heard anything by that afternoon, she called again.I also sent him an email on Saturday, explaining that I was contacting him on my mother's behalf and I was willing to make a full cash offer + $500 in closing cost assistance to the seller.

I live and invest in Kansas City, MO. There

Listed as a 3/3, however 1 bed and 1 bath are in a detached mother in law sweet.

We are in contract on a 3/1 sfh that also has a one bedroom studio detached "mother-in-law" house on the same property.  

I am not a commercial broker I hold my license for myself and investments, this was a friend of my mothers I agreed to help.

My mother in law knew I wanted to invest in real estate, suggested that instead of a SFH, do a 2 family or 3 family first.

There are paying tenants on the third floor, my mother in law lives on the second floor, we live in the first.
