I am so tired of throwing my money away to someone else's mortgage, but it's also the easy way out.

I in turn l learn I can sell assets (IE vehicles) and that will do. 

I was so tired of this area so I bought a new house in a nearby city.

Wow, that’s a really deep & difficult question to answer lolI’m just another dude that’s tired of sacrificing his time for money.

What is the best vehicle(s) to hold those investments - which is likely a combination of taxable and retirement accounts

Really tired of just passing up deals because the numbers just don't make sense and want to start getting in the game.

I've never used a lending vehicle other than self funding, so I really just needed to talk it out. 

That is a great way to go tire kicking and realtors will mostly leave you alone.

Cons: can be a dump for things like old tires, oil, etc.Much more of a day-to-day manual business than a small multifamily.

But if you sell your property now and just park your money, you will not see very good returns in any investment vehicle that is liquid and safe.You have a hold of a "golden goose" that will keep laying cash flow eggs and appreciation eggs for a long time.
