I'm wondering if it would make sense to source modular homes in China and have them shipped to and assembled in markets like Memphis, Atlanta, Birmingham, and other where you can buy vacant lots with utilities for as little as a few thousand dollars.

Others have found markets they like more.

Sure as hell beats paying $40k to an actor fronting for a real estate marketing company operating out of Las Vegas or Salt Lake City and providing guidance by a failed salesman reading answers from a script.  

I’m thinking rental but market is rough in Florida.

Future sale price is set, regardless of market.

Looking for insight into market conditions and any concerns for purchasing in Seattle.

Yes, it would be good if the seller communicated any issues earlier because then they could be handled/negotiated earlier if needed, but for the buyer there should be no risk to their EMD at least the way we would typically write a contract in my market. 

Hello, I am new to real estate investing and I have a tentative verbal deal on a pre-market lake property that I would eventually like to make my retirement home (10 years or so).

Maybe the market?

On the other hand, welcome to the housing market in 2024!
