With Great Credit and Great Income.My plan/question: -I want to cosign/co-borrow an FHA loan for 4-Unit with my brother.

With that in mind once you reach that level of savings you should be able to spend more freely.When you have more savings than you will need to take you to the grave you are ready to live less frugally. 

You can then participate in the CVS 401k as an employee of that company and separately in your own Solo 401(k) as an employee of your business (realtor).The Solo 401(k) can be used to diversify that pile of tax-sheltered savings. 

If you co-mingle with your own funds then it can be messy.

I say that just reading about the level of interest and people actually showing up.

lots of rabbit holes out there and what I call due diligence pump and dump scammers.. prey on mid level developers who have never gotten one of these loans.the borrower falls for the 5 to 20k up front fee to perform so called due diligence and the so called lender never closes.I have seen colleagues of mine blow through 100k looking for CHEAP money when they should have just under stood this kind of money in the Private equity world goes out at 10 to 15% apr period unless you have a local bank that will do it like I do. but even then its one project at a time and uber cautious.. they don't want to go back to the bad ole days were they ended up owning pipe farms.. and they generally will only do these with who they determine are their top tier clients.. you cannot in our market be unknown to the bank.. unless your have that monster balance sheet.but in my mind Socal is ground zero for this kind of money.. 

If you are installing on a concrete slab that is level and in good shape less than if you have an old uneven subfloor and have to lay concrete board down first.

@Justin PhillipIt sounds like you are considering a “land contract” or “contract for deed” —have a Real Estate attorney review it for you as your experience level in this kind of transaction seems minimal.
