Just ask any MFH operator who did an acquisition in last 18-24mnths. 

Account managers have literally no idea about day-to-day operations and glaze over specific questions asked to delay and confuse owners. 

Also it meets the 50% rule. 30 year mortgage at 7% is a payment of approx 323. 925 rent - 462 (operating expenses)= 462; 462 - 323 (debt service)= 139 cashflow.

Also the majority of those costs to covnert to a 2nd unit will need to be capitalized and depreciated, but some things (new appliances, flooring, paint, kitchen cabinets) can be shorter year assets vs. across the full 27.5 and IF it turns out that unit is > 50% you can use bonus as well on those items.

Usually only commercial properties with established operational expenses histories are evaluated by cap rates and then those cap rates can also be applied to buildings in certain areas representing higher or lower risk areas.

I would be careful about sourcing these types of lists from other operators, it takes awhile to build relationships with various companies and most of the company contacts don't like their information being passed around

There are different ways to structure this (writing them into the business entity and operating agreement, having them do a second trust against the property,  etc.).   

I'd love to hear from a turnkey operator here about the benefits.

I flew out to team build a few times, but now operate a full business that does about 50-60 properties per year with about 1 trip a year just to schmooze.
