I studied music from ages 6 to 17 but don't touch my piano so much now.

You forgot the great Music!!!

Franchises, College, Motorcycle Repair, Music Teacher, Import/Export, Amazon, Ebay, and on. 

And your tenants are Mexican?  

Has anyone ever invested or thought of investing in Mexican property?

That garage is going to have a lot of neighbors including the ones living in the house that won’t be happy with your guest puking and blasting music

And we don't get as much of them as we used to because royalty rates from online music really suck.

But when the music stops.....

These houses are easy for buyers to get into, they are expensive to maintain and the KB neighborhoods in my area stagnate; overgrown yards, old leaning fences, worn out siding in need of paint, foreclosures on every other block, loud music etc.

It's where I see lots of people in the music scene leaving Portland going to..
