There are many options, but your goals should dictate which action to take to take you closer to your goals. 

There really is no set value, it is usually dictated by your local market.  

Also, my community allows the owner to self-manage and some communities dictate the property management company.

Hopefully that advice helps dictate where you invest!

I don't want an Uber/AirBnB mashup wrapped up in an online monopoly sucking up the markets and dictating how it will work on their terms.

If sellers are dictating terms and have buyers willing to accept them, it is a seller's market.

Most will need to be under an institution due to asset requirements, but that can be in the form of a bond, I doubt it will apply to any attorney as you have already jumped through this and you're acting as legal counsel.States may have educational requirements to be a broker who will oversee or sponsor an originator.So, the level of sophistication and experience may well be dictated by insurance companies accepting the risk rather than a state determining qualification. :)

to"We can purchase your home quickly or in a flexible time frame you dictate, in cash, without closing costs or commissions and also without any need for repairs." 

Pre-qualificationIf you are too "Poor" to buy what you want in a neighborhood you are comfortable in, look at 1st time housing grants to increase your down payment amount so you can buy more house.The amount of the loan, and the amount of your down payment + grant will dictate a particular MAX purchase price for you.Be sure to allow for closing cost and loan costs in your calculations.Once you have that MAX dollar amount you can spend start looking at what you can afford in different neighborhoods.For instance in some cities you might find a Class D neighborhood 4 plex in good shape for the same price as a Class B neighborhood duplex.The Class D place might give you more cash flow than the Class B too, [BUT]Maybe your chance of getting robbed or shot or carjacked in the Class D neighborhood might be greater than the Class B neighborhood (so factor things like that in too).The question is still which should you buy--First whittle it down to specific properties the Bank will let you Afford--then make an apples to Oranges comparison as best you can.

AB1482 prohibits LL dictating substantial change to lease terms.
