I have a 3-step process I put them through before we actually agree to work together. 

The tenant has proof that the rent payment went through successfully and was processed.

As those prices fluctuate, there is a builders somewhere putting his feet up waiting to see a market turn more active because the last thing he wants to do is start paying crews to build houses, that could drop in value while he's halfway through the build process and losing equity halfway into the project.

That time I was looking at getting 201 S Washington (a 5 unit rental) and S Washington wasn't designated as STR and Gettysburg City said that I had to go thru the process of applying for zoning licence which is followed by a hearing with the neighbors as the jury who would hand me the verdict - yes/no.I like analyzing markets and observing them for a number of months/years.

One thing I'll add to an off-market deal is you might find a seller willing to do seller financing.You said, "I don't think the time exchanged to manage SFH would be worth my time and the cash flow most likely wouldn't be reasonable enough to hire a property manager.

That violates the Takings Clause.MD can be distinguished (in fact MD was mentioned in the decision) in that there IS a process on the books for the foreclosed owner to petition the court for the surplus. 

Quote from @Kody Smith: without getting too deep into my finances, what my strategy is...1. take loans to buy properties (leverage)2. fix/flip for day to day cash flow income3. use some of the fix/flip income to buy consistent cash flow through:- business acquisition, - commercial properties (MF and store fronts),I have no intention of doing ALL of the management myself, I will hire management as needed (medium term goal)my expected core role is money provider, evaluating the numbers, making decisions, and connecting with investors, wholesalers, lenders, contractors, and property owners.while I am just on step 2 of the journey, I am looking toward step 3 to stabilize, and not worry about if house prices drop mid project or not (or not worry as much) So to be fair this is more about obtaining and growing a real estate business not simply buying rentals for cashflow.

@Alex Washburn makes really good points - the process is definitely not easy. 

Sounds like you have a pretty poor security system.Even with a good security system, having a tenant provide ID is the first step in a professional screening process. 

No reason for me to go the through the hassle of the sale process unless there is some type of gain which the investor is open to and this is where I need the advice.
