The general consensus is just like you said - the inventory for distressed properties to BRRRR is dwindling down compared to a year ago.

This amount is compared to the assessed value of the eligible land.

It's also been completely renovated, although it's on the smaller size, square footage compared to other houses in the neighborhood (1,500 sq. feet).  

That being said my numbers were abour 5% down in 2018 as compared to 2017.

Maybe you don't yet have the 15% down but compare this approach to interest and fee costs of hard money lenders that can be from 8% to 15% around the country to this approach.

The upside positives are slight increase in rents, flipping electric & heat back to tenants, renting out the 8 storage units.The future rents , with increase, stays in line not to overprice..... compared to home ownership.The property is well in the 1% rule.

However, often you can make more cash flow from them compared to homes since you have 4 doors under one mortgage and even when you have a vacancy there are other tenants still paying which helps cover your expenses.

I figured if I use a different company for several properties it will be a great way of comparing them. 

To see if the expense of a rehab is worth doing look at sold listings near the property and compare bedrooms and comps of three bedrooms VS four bedrooms. 

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.
