Hi Muhammad,
It's a great idea to compare the markets and this is a million dollar question that I always hear from both sides. Even though you are doing the same "strategy" (BRRRR), the two markets are a complete different ball game. The type of properties, the cash required, type of projects and competition is not the same.
There's people swearing they are right on both sides between in-state and out-of-state, but personally if you have the option to do in-state, it's the best way to get started. Easier to stay in touch with the project and less uncertainty. The truth is in both market, you can make it work if you know what you are doing.
The ADU game is especially hot in Seattle right now so I'd look into that. Buy a house that's needs repair with a big lot, repair the house and build an ADU.
I've also heard from multiple Cleveland investors that contractors are very hard to find right now because of how many out of state investors have moved into that market.
