By themselves, improvements to property you own are considered to by personal property and not real property. 

@Jason Burkart To maximize tax benefits, consider buying the property as a rental and leasing it to your mother at fair market value (FMV).

There may be something called a "Due On Sale" clause.Check and see if all tax parcels are included in one mortgage or if they have separate mortgages.You have to have him spell out what he considers to be a "partial seller financing".

What factors should I consider when setting rent per room?

The seller has considered seller financing with 20% since this is a paid off property.

I would only ever consider this if the ceilings are already falling down or damaged.  2.

I think you can through BP or through the aforementioned REI meet ups more than likely.i am inclined to agree with a previous poster in that i'm not sure driving for dollars will necessarily yield you what you are looking for.Network with as many other MF investors as possible in your area and find an agent that knows the market and can at the very least set you up on an MLS search for your criteria.Coupled with BP's deal analysis calculator you can then begin underwriting properties you receive from the MLS with your agent or on your own to better understand your market and tailor your expectations moving forward.I'm an investor focused agent that focuses on MF and while we are not in the same market if you have any questions about moving forward with MF LTRs i'd love to see how i could help.

Consider using an FHA loan to secure a 1–4 unit property with just 3.5% down and take advantage of tax benefits by living there for at least two years.

Alerts I set up through sites like Realtor.com or Zillow.
