The very first day that a tenant is late, a Notice of Default needs to be delivered to the tenant (you need a receipt of delivery; if you hand deliver it, place it in a sealed envelope with their name on it marked 'urgent/confidential' and take a photo of it placed on their door). 

This seemed to be the most reliable way to find someone that I feel confident is good and knows real estate. 

I'm sure there are many more experiences where the contractor hasn't fulfilled their scope of work and gotten away with rushing the project to meet the deadline, And, I don't want to be as naive to say that I'm that 1% who can have complete quality/operational control, but I'm confident I can establish a system and hire independent inspectors to review the contractor's work. 

Financing: I'm confident I can put $10,000 down as a down payment within the next year.

I consider these info be confidential and am reluctant to give all these info to them.

Kieran, the best bet here is to refinance with a DSCR loan.

Mediation is a process in which the parties meet with an impartial person who helps to resolve the dispute informally and confidentially.

I wouldn't bet my life on 50%, but I would bet they are more problematic than the typical long-term renter.

Your best bet is to find and contact all of the top local wholesalers and go to work for one of them and see what they do right and wrong and see if it's even a business you like.

12 or 24 Month Bank Statement is probably the best bet.
