My goal of refinancing was simply lowering our monthly spending to reallocate towards future investments.

The couple's current rent is similar to ours The sister is has no rental history due to a recent divorce.We're torn given 2 out of the 3 people have lower credit scores and it's not a family moving in.

The market has a lot of strong points right now: affordable entry prices, great rent-to-price ratios, and high demand for rentals, especially in the Section 8 space.What’s even more exciting is the direction Detroit is heading.

I made a relatively low offer and after one negotiation we settled on a price that was about 45% lower than the original list price.

Not sure if it had something more to do with pandemic response to move to lower priced areas or what the motivation was.  

But if you’re looking for a more stable, family-friendly environment with lower costs and a focus on LTRs, Texas could be a better fit.Since you have young kids, I’d dig deeper into school districts and neighborhoods in both states—family life can really shape where you’ll feel at home.

Go for a lower downpayment. 

A lot of 'off-grid' places are not, which will lower their value and resale ability.Also, you are decreasing your potential market by choosing a venture like this..not everyone will find composting toilets as cool as you and I might.Having said that, I think it could be a great find, if it check all the the boxes.

So your $10k could get you a property but what you don't think about is the tenant class is lower and the ups and downs are more frequent.  

So, yes, you'll get a lower percentage of the cash flow (which isn't that high anyway for long-term rentals like pretty much anywhere in the world, including the US) but you'll get appreciation and loan amortization.b) You successfully invest in STRs and make enough money that you don't care that much about the higher taxes.To conclusion, as a foreigner investing in Spain, with a few exceptions of specialized niches, I focus on areas that have (high) capital appreciation and short-term rental potential.Hope this helps.
