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. 

Recently, with two separate inquiries (different dates, different groups), things didn't work out.VRBO Pre-Approval blocks those dates in your calendar for 72 hours. !!

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

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

Between Oregon and AZ residential and commercial we have around 23 units with only a couple of small loans.

There's a couple things you could do.

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.

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

A couple other things that I would recommend clarifying is that they will be responsible for the permits, both opening and closing them. 

The arrangement works out fantastically, as all parties can now do what they're best at, and while we are separate entities, our services are integrated.
