We receive the MF statements and talk about holdings, share price, why it changes etc when they ask.The other thing we did was hire them to work on properties. 

Do do you think medium/larger multi-family is a feasible strategy here in Detroit?

In my mind, if they can pass a background and credit check (which they pay for in the application process), give references (that are actually checked), submit a complete application, submit the last twelve months of bank statements (which show the rent paid previously), and can come up with the deposit (first and last month's rent), then let's move forward. 

Hello, so I am still fairly new to wholesaling in Detroit and I need some advice on what to do when a seller asking for proof of funds/bank statements when I do not have the money?

So for a 1031, you keep upgrading to larger properties each time.  

To me Craftsman Style porch columns make a great statement. 

My long term goals are to utilize the BRRRR method to build my portfolio out of state (Arizona is currently a bit too hot, pun intended), and eventually move into larger deals. 

I don’t know if it has a direct correlation with the growing “young professional” demographic but I think many people would be surprised on how many 1 occupant tenants there are renting larger units or 2 bedrooms units to serve as an office. 

the larger banks may not have their systems setup for it?? 

When applying for a mortgage (making assumptions here), the lender will want 3 months of bank statements, W2s, etc.I agree with others here that house hacking (living in a house you are renovating) is the way to go AND in your situation, buying a duplex or similar income producing property will help if you apply for a mortgage.
