Our real estate portfolio included multiple Single Family Residential Flips, a commercial building (office/shop space), and a triplex in Canandaigua, NY.

I don't like the conflict of interest this comes with, but I can see the benefit as a buyer of getting access to properties that the brokerage is selling.

It has ample basement living space, that the tenant uses as a third bedroom.

Is the basement legally considered living space?

Wish you luck in this space! 

Nothing wrong with this approach but what you want is a measurable, predictable number of potential deals flowing your way so I wouldn't recommend relying solely on the passive deal search.You may have access to information to help you prospect for these deals on your own.

I have access to RentRedi and REI Hub via BP but a preliminary search has not turned up much.Any guidance would help, thank you.

I have, in some cases, seen basement space totally ignored in valuation.

So, the extra unit may cost you more then it brings if you cannot access equity or if the market discounts the property when you go to sell due to financing available.

Do you work with any specialty tax firms to help us small business owners get access to R&D tax credits, cost segregation and other specialty tax credits?
