If you need X,Y and Z to become successful, it is completely irrelevant if you have A, B, C, D, and E... stop asking how to become successful with A, B, C, D, and E... and start figuring out how to get X, Y, and Z.So to answer your question, can you wholesale a listed property?

Millennial Demand for Housing is Up, With Gen Z Right Behind2.

It could be worth $Y down the road if you spend $Z to fix it up and raise the income.

Typically when I write letters for these types of properties I usually include some wording like "based on the proposed DSCR of the subject property @ ______" and "this approval is contingent upon a review of x, y,  and z on the subject property".  

All,We have just secured an offer for a property in lansingburgh area and its a full A-Z renovation.

I've heard others say they wish they would have done X, Y, or Z knowing what they know now.

I'd start by connecting with local real estate agents like @Eudith Vacio, @Edgar Barbosa or @Henry Lazerow.As far as next steps, I always like to use the ABZ formula -> A = where you are now, B = Most important next step, and Z = final destination  

We love to build our own new constructions because once we put together a new construction team that can take a project from A to Z, the project costs less than a resale, and you get brand new properties with a very small maintenance cost and insurance premium.

Sounds like you’re not in a real bad relationship with this guy yet, so maybe try to have him fix stuff and have an attititude that you’ll pay him if he fixes xy and z.
