i wouldn't tell you where you should move since i don't know you.also, a lender would be in the best position to advise whether you qualify for a specific loan. 

By purchasing properties in high-demand urban areas such as Berlin, Munich, Hamburg, or near military installations, American investors can generate reliable monthly rental income.

They want you to close very fast so my clients couldn't use hard money loans.

You've got to include loan pay down, appreciation, and depreciation in your return calculations.The point of cash flow is to keep you safe.

Lenders report a huge uptick in new loan applications.

The balance on my bridge loan is $120,000.

Somewhere in the middle is likely your best bet for a 20 year timeline.I have almost 50 units here myself and that's about what my portfolio is cash flowing at this point combined LTV is around 65% as loans have gotten paid down and values have went up.

The terms for a 2nd position loan on a rental is 6%, 25 year term,  and 2 points origination fee.  

This seems to be a VERY good deal for a BRRRR and I think you should be able to find a local lender (bank or credit union) that would finance this with a DSCR loan.

I have researched the different kinds of loans for this but I would love to speak with any lenders or other investors in this area.
