Residential Property with storage units

[Eric Davenport]

Hey everyone,

I am looking at a 3 bed 1 bath house with 10 storage units on the property in a residential neighborhood. When evaluating the property would you use comps for the house and units, the income approach, or a combination of both? 

Also, what would be evaluated when refinancing a property like this, would the banks take into account the storage or only the house? If it's possible, it would be really cool to BRRRR the house and storage units (add new garage doors, locks, etc) and add value then refinance.

Thanks!
