I take a long term approach to investing and intend to put $ 200 - 500 a month into an account myself as the best deals are all cash in these areas. 

It's a program with lots of hoops and accounting extras for owners. you can charge a late fee if the renters portion is not in on time. 

I'm firm on the down payment I've offered her, so I'm not interested in using that to account for the loan issue. 

Account Closed Thats a pretty old article from over a year ago. 

However, 1. my calculated annual expense is lower than the listing agent's estimation.

Give them notice of your intent to foreclose as well within a specific time period, then get your attorney to start the process (it could take some time) if they don't pay the account up.

I have my business (LLC) account with Bank of 'Merica.

I think I am starting to figure this out due to all the great help here on BP and some great books on SDIRAs too, but just want to make sure as we are some serious talks with a motivated seller about our next purchase...

Totally agree with @Tom Mole and Account Closed.  

A preliminary Team includes Attornies, real estate Agents, CPA's (or accountants), Inspectors, General Contractors, and Handymen.Always remember to do a math analysis and try to look at prospective properties before you make an offer or at least have a clause in the sales contract that allows you the time (about 15 days) to make a detailed inspection and possibly back out of the deal without a penalty that will hurt you very much.
