To further expound on his story, the commercial space is not as difficult as advertised, but finding team members with alignment of interest is the hurdle.

The biggest hurdle is getting the capital upfront for deals.

Unless you think it has termites, want to sell to someone else and are looking for your own way out, or gave them some unreasonably long inspection period like a month or two. 

But it depends on your goals.I had never owned real estate before of any kind and so that coupled with buying out of state was a large hurdle to get over.I decided to go with turnkey to start and I don’t regret that at all.

This does present a hurdle to RE investors when they are first starting out because most of these new RE investors  do not have much excess cash to cover a large capital expense (or even a moderate cap expense). 

I'm in San Jose working with a youth corps programs that is starting to do Tiny Home construction and we are reviewing all the regs etc for California -- the hope/goal is to make quality homes to service our homeless population then the community then eventually FEMA etc...These will be on trailers - Our approach will be to approach members in the community who would like to have the extra rental income by having on elf these on their property -- no doubt there's a lot of hurdles ahead of us but we have a record of building/construction - the challenge will be the market and regulations  which I guess always is the case....

coming out of Comfort Zone is major hurdle...As Gary Keller's quote on his book... " Anyone Can Do it...Not everyone will..."

Were there any hurdles you had to leap because the money came from outside the U.S.

A prudent landlord would call the AC guy to schedule for the first reasonable appointment and show up within the hour to drop off window units or portables.The law doesn't require you to treat them like you want to be treated because that is an unreasonable and unknowable standard.
