I agree that vacancy may be low given it's a student rental (assuming there is strong demand in the area) but there will always be some vacancy.What updates have been done to the property?

I'm wondering if higher owner occupancy rates means that there is little demand for rentals in the area or if it means that there is a low supply of rentals in the area.

Sub2 in general works best with pretty, low equity houses where the owner has become a sudden seller.

Since I've never lived in my rental houses (and I'm paying abnormally low electrical rates when these are empty...just to keep the frig going, air when showing a place, a few lights, etc.)

Kay, dependent on the income level the units are in can make a difference of percentage and also the number of units. 

- Level of prescreening performed on buyer before they can view the property- Who is best fit to handle the coordination of the showing, contracts, and closing? 

I can purchase it on cash basics but I don't want to loose this property if I bid to low .

Im really not a fan of your plan, are you unable to borrow at a bank, the Commercial lender at a small community bank generally can close fast and at a low cost, I can do 6 mo ir 1 year Interest only at 4.5% on a 20 year amm, i need 20% down and fund fix up, but they would also do a loan based on ARV, and you put 20% of ARV down an they fund purchase and fix up.   

All of our properties are fully renovated, including upgraded electrical, plumbing, water and heat, to ensure low cost on future maintenance.

I've also read Brandon's book "investing in real estate with no or low money down" and his investing for beginners books a couple times.
