At 10% APR interest for 1st position purchase money only, you'll have experienced flippers beating a path to your door and you'll sleep like a baby at night (and no, that doesn't mean waking up screaming every two hours).

As far as we can tell they only have one person that does everything, with offsite help brought in when needed (when the customers are screaming!). 

My question is: Is it legal for me to rent the main house to one family and the in-law unit to a single person (with stipulations on no or low visitors, noise etc).

The difference is whether you move on, or you wail, scream, and gnash your teeth instead.

(after calculations ill cash flow 500.00 monthly)Ive been working on the property and i had a visitor the other day.It was a R.E. agent asking to see the unit..i said check it out!

If I see another new 26' x 36' cape with a breezeway and 1 car garage I'll scream.......

If you were able to contract a property at a point where it’s a screaming deal, you’d have no problem lining up buyers.

I know many visitors were waiting to hear about this before committing to anything. 

The mining companies screamed bloody murder.

Calibrate the color right, and you'll have a house exterior that welcomes visitors when they roll up to your home.The right color scheme will give you joy every time you return home for years to come.Goodluck!
