Said it was one of his tax clients & would not give me their name.

Check with your municipality about how property taxes will change when you buy the place.

How much money, after expenses and taxes would he property make yearly?

Thanks again for your input, and I'll probably reach out as I get further along in the process.Hi @Edward Zachary Samperio, the regulations aren't that difficult and I'd be happy to give you a quick rundown about the density limits, hotel occupancy taxes, permitting, etc.

Zero capital gain tax, next to zero income tax, property Tax is super small.  

I was curious about Lendbase already prior to reading this post.

This is obviously much better than $1,400 per month.On top of that, you will now get 2x the depreciation write-off so your taxes should go down.On top of that, you will now get 2x the appreciation when real estate price go up.On top of that, your tenants are helping you pay down the loan, initially at about $100/mo for both properties, which gradually gets better and better.On top of that, you now have more units so if one or two goes vacant, you have more renters covering the losses of the vacant units.If you want to keep these properties, I would do a cash-out refi and go buy more rental real estate.

With down payments as low as 5-10%, plus low property taxes compared to the U.S., investing in German real estate is more accessible than you might think.If you’ve ever thought about owning property overseas but felt intimidated, stay tuned.

Overall, the tax benefits and appreciation alone keep me interested in staying with it more than the cash flow itself. 

A rent payment isn't enough to cover the DSCR payment, HELOC payment, tax, insurance, and maintenance.
