I would develop a ruff estimate of all needed repairs/deferred maintenance requirements.  

The goal is to create capital to begin developing passive income, enough to start planned investments. 

Obviously, it would be ideal for me to know when they receive a NOD, but I don't know how to obtain that information.

Through out the whole interview not even one qn was asked - as to what are the real practical roadblocks are .Anyway - question everything , keep learning , develop emotional intelligence .

Labor and capital are really the only two methods that generate income.Fix and flipping, along with property management, wholesaling/brokering, or developing (among others) are really jobs. 

Incentive of some sort for tenants who constantly pay their rent on time or are the "ideal" tenant?

You also are only Cash Flowing less than $100 per unit.The ideal BRRRR deal would end with Zero of your cash left in it.  

Ideally personally I’d keep my overall portfolio at 35-40 percent equity.

The land alone in those areas is 500k to 1 million an an acre before building the structure and profit rolled in on resale for a developer to sell to an end buyer.

Another development, he hasn't replied to me since this Wednesday and today sent me a text with another story apologizing for not responding and decided to send the $50 late fee (which I received).
