Why don't you use a bit different model where your potential clients can pay perhaps $250 (or a bit more if reasonable but no more than $500) for an hour meeting to talk to a real CPA who has been trained by you and determine whether or not they can save me money on taxes such as capital gains or ordinary income or passive income by forming structures that makes sense for using up various deductions and write-offs to the fullest extent to off-set the various sources of income and let them show me how they can eliminate my taxes down to minimal to zero in that quick session, it is like a preview session to what is possible given my actual data. 

Keep in mind that while cash flow may be minimal if your mother lives in the property, potential appreciation could still make it a viable investment over time.

For shared living spaces, durability should often take precedence over luxury to minimize the need for constant repairs.

Pointed out downspouts not being long enough, flaking paint (minimal), windows that are older, provide furnace reports from HVAC tech, "remove sliding latch from bedroom door" to name a few. 

Otherwise, you can re-stain them with a close enough color to minimize the amount of rework.

Diversify investments across asset classes and locations to minimize risk.

My initial criteria is to look for newer built houses to minimize maintenance and upfront cap expenditure on major items like HVAC, Roof, Foundation etc..

Generally there is a very minimal difference in rate between ARMs and 30 year fixed mortgages.

I have 12 properties but only cash flow $2000-2200 and that's saying they are all rented with minimal repairs. 

He also feels there is minimal impact and will continue with the coin.
