Also <most times> adding a extra bedroom but not adding sq ft doesn’t help much on ARV specially currently being under 1,500sq ft.

I thought it might be looked at as a 2 bedroom if college kids use it to split the rent or something.On the other hand.

- You can rent out the bedroom you would normally occupy.- Most cities do NOT care if an owner lives in basement, but will not allow a tenant to unless baement has legal egress window.3) Check local statutes if any limitations on how many unrelated roommates are allowed.4) Check with local building dept to see if rental inspections and corresponding requirements.5) Local statutes allow locks on bedroom doors?

**I'm wondering specifically about:- Cost to furnish - do you work with an assumption based on the number of bedrooms? 

Check the section 8 checklist and be sure you will pass (do you have a lead cert if you need one, do all your bedrooms count as bedrooms, anything weird about the house that won't pass inspection? 

New addition built to add a bedroom, bathroom and walk in space along with a wood deck in the back."

Have no more than three bedrooms.

If you have a 6 bedroom in an area that does not have a university (students looking for shared space) or is in a family friendly place it may sit vacant longer between tenants.For Capex, try not to use a generic number - look at the roof, furnace, hot water tank, kitchen - when will each need to be done and what will it cost?

A ceiling in one of the bedrooms need repaired as its "sinking" in.
