All of which has lead to doubling in price of lumber, drywall, and many other supplies.So flippers, or investors using BRRRR..... basically anyone who does rehab to their properties after purchase.

Seems like such a small amount to go through a double closing or even an assignment. 

Well you missed the double or triple over the last 4, 5 6 years in Cleveland, however I do not see things slowing down, there simply is no inventory .

"Double master suites" or "dual master suites" are probably good search terms to begin with, especially if one's downstairs (better for a mother-in-law JADU) and another's upstairs.

It was hard to get good comps because there’s not many homes in the area that sit on a double lot with a side driveway and brick garage.

Also, when I run the numbers with both sides rented out should the expenses be doubled since it’s technically two doors?

Loophole is a matter of opinion :)  A bigger problem is double-reporting of the same income via 1099-K and 1099-NEC/1099-MISC. 

I'm mostly interested in the CF and realized NOI per year for each market after property stabilized with a mil acquisition.With 3-4% cap rate in northern CA, if you buy 1 mil (none) or 3 mil apartment, it never makes money except thru appreciation so I guess double-digit cap what perhaps matters rather than the price.

Attendance has varied, we've had double digits a few times. 

@Marc Rice so a double mortgage?
