If you want something way more accurate , you'll have to pay a premium with tools from thomson reuters or transunion, they are also highly monitored from an identity theft perspective. 

The good ones are worth their weight in gold.You've gotten some good answers here, but I recommend not substituting the forums for working with a tax pro who understands the full scope of your tax situation.Anyways, good luck with this!

- How will you monitor quality of work?

. :-) Your personal opinion carries no weight in court.

The checking account will draw against and pull from your line of credit to deliver your funds assuming your line has availability still (debit to line and a credit to your checking account).I’ve experienced , utilized, and have monitored how these tools work for over 10 years+ in practice and operation. 

MD suburbs have opportunities to do more than small positive cash flow while also being able to closely monitor your investment. 

Analysis, plan, monitor, action, rinse & repeat.  

Focus on Health & Safety First • Electrical hazards, roof leaks, HVAC issues, or plumbing concerns carry more weight than cosmetic items.

I wouldnt give any weight to what you've already spent on the property.

Or in this case 10 @ 10%, you do 2-4 at large weights and understand how the risk sits.
