There are already areas of the city that have started the rapid ascent.

There are areas that are booming, with lots of new construction and rapidly increasing property values.

The next step in my evolution will be multi families. 

She likes to come up with a package and show 4-5 homes a once, and doesn't respond rapidly to popping out to show a single home that is a fixer upper for an investor.

Since  MFH is valued on rents it would seem that selling prematurely is a huge opportunity cost.It definitely seems like exchanging into some multi family before a crash just to preserve value is a good idea, but selling rapidly appreciation Seattle area real estate prematurely seems like a huge opportunity cost.

I'm considering partnering with an investor on an out of state rental, single family home in Grand Rapids, Michigan.

If the home is a double wide OR a number of pop-outs, add-ons, or sun rooms then the price will go up rapidly.

I use foremost out grand rapids, mi.

Grand Rapids in particular. 

There's a housing affordability crisis due to the influx of relocations that happened from 2020-2022...so rent increased rapidly, but its leveled out.
