I'm new myself to REI and have been bingeing on books, Audio Books, Podcasts, Blogs, etc. 

I've been eating up paperbacks, audios and podcasts.

There are 12 units that consist of 1 bed/1 bath and 6 units that are studio/1 bath.

I also listen to Audio books as well.

It’s a 3bed 2+ bath with a detached garage that was converted into a studio with a half bath.

Kids kept living with parents, roommates vs studio, etc.  2. 

I currently have a studio that is a 10min bike ride from work.

I bought a 2 bed 1 bath town house I paid 25k for it I put 45k rehab is already rented 1,200 month the appraisal company says they can’t appraisal the property because I converted from 2 beds 1 bath into a multi family 2 bed 2 bath and a fully studio in the basement so they don’t have comparable home in the neighborhood plus I didn’t get any permits for the rehab I know is my fault but I would like to refi my property and move on to next one.

I'm intrigued that you could get a studio in the garage of a condo.  

In terms of rehab cost/benefit, attracting and keeping tenants, and resale potential... are multiple bedrooms per unit in a multifamily generally more desirable than single bedroom or studio units?
