I actually tried Cherif Medawar's program and have found Licensing Experts vastly superior in a couple of ways. 

There's a couple things you could do.

Now you might be like Joe, know rents for a couple of neighborhoods and can quickly estimate expected cash flow from properties pretty quickly (that's what I do as well) but you still need a screening rule so you invest minimal times on properties you will never put an offer in on. 

There are a couple of $100K lots available, and I’m trying to think of alllll of the possibilities.

Here are a couple of developers you should take a look at Trion Properties, their principal Max Sharkansky posts here on BP, https://www.biggerpockets.com/blog/top-5-markets-multifamily-rentals-2019and Feldman Equities out of Tampa (3rd generation real estate family famous for having built the terminals at Chicago O'Hare) who are among the only ones opening up downtown skyrise office buildings to accredited investors.

They've experienced a couple of murders I think in STR and some prostitution problems. 

It takes longer to realize, but the gain is worth so much more than a couple hundred dollars of cash flow a month.

I’m also from the US so I follow that market and am soon to be involved with a couple of exciting projects in Seattle & San Diego

STR internet guru's seem to be coming out of woodwork the last couple of years.

There were a couple of variables at play like time of year and agent showing the property..3.
