Will residents of studios or 1 bedrooms now want to move up to larger units?

I would love for this one to be a duplex or 2 bedroom house in south Minneapolis.

It's a 5 bedroom apartment, 3rd floor unit. 

The bedroom had a light fixture they did not like and they wanted to change that to a fan.Landlords do want to know about leaks and get them fixed, and as soon as possible before they ruin a cabinet or flooring or cause mold to grow. 

Real estate values do not change overnight especially when there is ample demand and low inventory.

@Bryan Scibilia Definitely worth the upgrade if the duplex has 2 or more bedrooms in each unit.

Also any rough estimates on average prices for rehab costs per bedroom, bathroom, and also adding bedrooms or bathrooms in the Little Rock market? 

I’m looking to add heat & cooling some kind of way but the only thing I can come up with are doing mini splits in the bedroom & living area which will probably cost around 3k + , another thing I thought about was just focusing on the heating part since the basement usually stays cool even when it’s super hot out in Georgia .

I’m looking for rental properties I would like to hold for long term.Cashflow over appreciationLooking for home with 3 bedrooms & 1+ bathrooms 1100 - 1400 sqft In a C or better neighborhood Under 70k Deteriorated property preferred

I'll be getting an FHA loan, attempting to rent out a couple of the bedrooms for the year that I am there to come close to breaking even, then renting out the entire house to a group of students in the following years.
