With the exception of building a trailer on the property (these are hard to finance), this sounds like a good plan AND if you are using it for your business AND your business pays more than 50% of the rent (if you have more than 1 tenant), then this is a more financeable property in the eyes of banks and credit unions as it would be consider a commercial "owner-occupied" property. 

I would stay away from section 8, pull credit and background, and call referrals, and look at pay stubs for everyone who applies.

Besides that, I have a credit repair and funding company that helps entrepreneurs get their businesses going.

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.

I prefer to have the least amount of banks as possible.Create a bank account that you already have a relationship with(Credit card or mortgage)The least amount of bank accounts is also ideal.

Sourced through the MLS and negotiated heavily with the seller to get price reductions and credits at closing How did you finance this deal?

Personally, I'd cash-out refinance into a 30 or 15 year loan.

If you have nothing, and make nothing, you declare bankruptcy, wreck your credit and try to go back to renting.

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?

Personally I like to build with cash to avoid the extra expenses, so I dont actually finance anything until its done and I have decided to hold it.
