Then, I'm also wondering about the challenges.

When there's tenants already occupying the property, there's often times different leases that were signed among the tenants.Additionally, renting by room usually sees higher tenant turnover which in turn causes more work for the PM.Other challenges to consider:- Disputes/conflicts among tenants (different personalities if a tenant doesn't know the others prior)- Occupancy limits- Splitting utilities (what if someone uses more water?)

Challenges?

Challenges?

Next in this environment you may be challenged to get $10k rent on $1.3m property.  

I am not sure this would really lower pricing that much, but also frustrate more and more borrowers as sometimes its very challenging to deal with banks and lenders.
