I believe I can invest and then take out whatever I have to pay the IRS next year so at least it makes me some money before I part ways with it.My long term goals are just to wealth build with my cash.I dont plan on needing anything for another house, college, etc any time soon.I may buy a car and travel but again I can take that out of the brokage account when I needed so at least it makes some money till then. 

I own multiple LLCs and partnerships, and I’ll be moving between different houses over the next year.

I'm an investor myself and moved from Portland OR to Columbus OH to start house hacking.

I am a rookie investor working on building my portfolio and a structural engineer offering consulting on any structural concerns you have for houses you may buy, or if you want to know out a wall to open up some rooms in your next flip. 

Ive been trying to decide between; flipping a house that's on the market, flipping a foreclosure property, building a spec house or doing the BRRR method.

I initially was going to do a commercial loan and purchase my next house as an actual investment property, but financially it made a lot more sense for me to move into it and put a lot less money down upfront and have a lower interest rate.

I bought a 7 house portfolio from a private seller.

This includes property management, purchasing houses, etc.

Does anyone know the going rate for price/sq ft to construct a beach house?

In our market that's solid base hit given the higher rates and lack of supply. 98% of the houses I see negative cash-flow without creative opportunities (MTR, STR, rent-by-room) or BRRRR.
