I have good credit, less than 3-4k/mo in revolving card debt and personal overhead of lower than $2k per month. 

You are missing the most important question and that revolves around the integrity and track record of the sponsor...the deal is secondary.

You should run all leases, CAM utilities etc as you can to season the LLC and the property so when there is enough equity in the property to refinance into the LLC with a portfolio lender.

Are there any banks out there that will offer a revolving line of credit on an investment property?

Operating funds are separate from cash reserves.Operating funds = Checking AccountCash Reserves = Savings Account or Money Market AccountMy reserves are in a revolving account - property tax reserve for each property gets paid out/trued up twice per year (when I make the payment.  

Generally retail has higher per sq ft lease rates and are on triple net leases (base plus cam).

Mostly revolving around financing the deal.The property is a duplex listed for 99K.

If you self manage you still charge them for a property management fee at market rate built into the lease correct and CAM cost above base rent?

Fetish cam model? 

I recently cam across a duplex in my are for 105k, needs rehabbing inside and out, its been on the market for a good bit of time and my business partner and I are thinking about putting an offer in.
