I use this property and another one as my business line of credit. 

The better the rates, lenders generally want to see more experience, higher credit, occupancy and DSCR requirements. 

A company that specializes might be a good idea, but if that isn't practical because the potential difference in taxes isn't that great it is something you can do on your own.

What value is expected or provided by an agent who specializes in multi-family residential, not commercial. 1-4 units.

The most important rule is to have the cash flow of the new property be able to pay all its expenses, mortgage, AND the line of credit back.

Again, different strategies but in my opinion the larger you get the lower the risk you want and as others have pointed out I think your deals in the build to rent sector or with larger tract builders is where we focus and probably others as well. maybe this was a special deal. in a few weeks once we get the appraisal back on an infill lot we have I'll show you how we made almost a million dollars on a site that's 0.1 acres and urban with very little risk backed by appraisals. we didn't have to wait 18 months or invest 500k either. we barely needed a capital partner too and every deal we entitle we would develop.

You might find a local credit union or community bank that will go to 95 -100%.At one point I called 2 different VA Regional Loan Centers regarding this section in the VA lenders handbook:Assumability - The second mortgage should not restrict theVeteran’s ability to sell the property any more thanthe VA first mortgage.

You need to have reserves in either cash or credit regardless of the situation. 20k can go away in a blink.

and for the life of me I cant see what these guys do that a very good RE broker who specializes in those assets could not do for you and far better frankly. 

All investments and assets are in the name of the special purpose LLC instead of "name of custodian FBO Jim Bob's IRA".5.
