@Brent Tomczak - even after you file 2016, it sounds like you will not have any rents considering you haven't finished the property yet.

Age of property, square footage of building, square footage of lot, number of bedrooms, number of bathrooms, garage, carport, off street parking, qualify of finishes, etc.But, I would say square footage of the building is number one thing to compare.  

You could market at different price points depending on finish etc.

I stood on the land and in my mind, I saw the entire finished building down to the color scheme and interior decor.

Have him tell you exactly how much money it will cost to finish.

Also, how did you attain these prorated rents at closing?

Hello...I'm a beginner Real Estate Investor...I don't have all the answers but I did just the other day watch a video with Brandon that is finishing up this type of deal...actually he was recording the video at Starbucks...if i remember it correctly it was title...Investing in Multiple Family Homes...hope that can help u once you find the video...it is with Bigger Pockets...

I finished my classes in just three weeks, and passed my exam just a few days later, so I know there is a lot to learn to even get myself out there, and I am ready to hit the ground running. 

If your son has finished his degree recently, he can be eligible with short working history.

But this also gives you time to finish the repairs and get a tenant in there to start paying your mortgage.
