I would be wasting the money I paid to have the contractor look at it.How have others gotten around this hurdle?

When I found an owner they were usually unreasonable.

It further goes on to state that if there is a case of discrimination brought, and you do have nongovernmental occupancy limits, they will determine id it is done to unreasonably limit or exclude families with children (protected class).Of course, this is federal and your local laws may differ, and in fact, there is some states that have laws making it illegal to set your own occupancy limits.

I’ve heard a ton about crowdfunding and how its a great gateway into BRRRR’ing a propert but no ones has really elaborated upon some of the hurdles a first time invester can and will face.

So if I start with a duplex or a quad as my first property my goal would be to have a net cash flow of $500I intend to use the "BRRRR" (Buy, Rehab, Rent, Refinance, Repeat) method but have never used this strategy before so I still have a lot to learnIf I only close on two deals starting in 2019 then I will need to find another 20 deals in the remaining four years (2020-2024) that also meet this criteriaBeyond 2024 I plan to continue to scale even more over the next 3-5 years with an end goal of financial independence by ~2030 (meaning that I will not work a "day job" but will passively manage my real estate portfolio)Biggest hurdle: I'm going to be living outside of the US for the next 3 years and will (likely) not be able to physically see any properties that I plan to purchase.

If you remove that hurdle, you can move up the price, asset quality, and tenant quality.

Say the pad is $15K to $20K, then out of pocket of $4K is not unreasonable. 

What are things to look for that would make buying it unreasonable?

Those that navigate it can make a ton of money, just prepare yourself for a few hurdles!! 

Those folks run a sophisticated operation, and if we don't keep up with their level of sophistication (and exceed their customer service) we would lose business to other investment classes that treat their investors better.Perhaps it could be said that the competitor to TK firms is buying homes directly, and that competition lacks sophistication--thus the hurdle is just above that level and anything above that is good enough.
