@Thomas Youngman I am excited to find this thread!

I would also find a good GC to bring with you to verify rehab and dial that in. 

My stock portfolio has compounded by 45% annually over the past several years and I routinely take profits and derisk, go into cash and then back if I find deals.

It's been a long-time dream to do a new build and so I'm actively working to find land and begin the process.I agree that the profit margin you post seems very small.

I recommend that you find a trusted or recommended Mortgage Loan Originator (MLO), who can give you options for property-based loans (mostly investment loans) and they don't use your taxes but the P&L of the property.

Listen to podcasts, read books, and if you plan to invest in the Netherlands find some resources that speak to that market specifically.

I have searchd the forums but couldn't find much about Boostly. 

With that said, I've done some research on the market and found the following information helpful in my considerations for Phoenix that you might find helpful as well:  Demand for both buying and renting property remains high due to the city's strong economy and growing population. 

I am thinking of getting a list of leads and using the owner info to mail postcards or letters to find small multi family.

If not I would suggest finding a servicer to collect and manage that note.
