How would you allocate the $7k per unit to increase rents?

@Bruno MauroCurrently expenses are allocated between personal and the room rental.Then the personal will convert to rental when you rent the whole thing.For Lowe's, record at cost, not market value.

@Lucien GautreauFrom a tax perspective, you want to consider purchase price allocations.

If your house is a rental FIRST then a primary you face qualified use allocations when you sell. 

Or allocate it if you are using part of it to pay expenses.

No, I don't see it as a good allocation of effort or capital for my particular business.

With the kind of equity you'll have coming out it's also not a bad time to be looking at some defensive investing and allocating your proceeds strategically to lessen your correction exposure. 

On your shared square footage you can allocate and deduct that % of all normal rental expenses.

You didn’t mention how much of a down payment you were making and I didn’t see Cost allocation for vacancies, CAPEX, or maintenance.

That could justify low repair allocation if so.
