I am counting my blessings!

I expected to see the same kind of returns as my other property, but my best intentions and optimism don't count against effective calculations and market rates:)@Darius Ogloza So the $60 reflects my current HIKED rent rate...

There aren't necessarily certain attributes/characteristics that prevent deals from being worthwhile, unit count or otherwise.

Clearly, the child's use of the home is counted as personal use by the owner.

I feel that the appraisal could have included higher comparables that have similar bedroom and bathroom count.

This puts my personal DTI around 48% when not counting her income. 

Decided to try what @Wayne Snyder suggested for Ada County, The county assessor website does provide gis files for all parcel within the county as well as unit counts for each one.

Yes you will need to have good credit, good dti ratio and rental history if you want to count your rental income in the dti calculation.

Makes it easier to save and less capital tied up in the deal.It really depends on the lender and what percentage of your rental income they count for.

I think the other posts have pretty much covered it from a rental perspective, but another issue is the financing.The room will not be counted as a Bed Room (BR) for financing purposes.
