Under the Dodd-Frank Act, if the loan will be secured by a property that the borrower will use for residential purposes, then the person who makes or arranges the loan would be defined as a “loan originator,” and must have a mortgage originator license.However, Dodd-Frank doesn’t apply to non-consumer buyers, so (for example) if you want to loan money to an investor who will borrow under their LLC to flip a house then you’d be exempt from the mortgage originator license requirement of Dodd-Frank.But since you’re in California, there are state laws that apply.

When applying for loan for new construction, I have to provide a take off (estimate), with soft cost and hard cost, with a set of plans.

Be sure to find out whether those fees would apply in your case, since they're not yet included in your numbers.I don't see any budget for vacancy, cap-ex, or repairs. 

You could apply kilz on the shared wall and see if that helps.

Thank you, I will absolutely apply that - “more is not always better”!!

You should apply any money coming in to the fees owed then the rent.

If you have a partner - do it together.See the following post with advice that also applies to ANY strategy: "unless you have unlimited funds, your strategy HAS to allow you to get your money back or else you will run out and have to wait a LONG time before you can buy another property."

I’m doing so you can apply the same processes to other markets.

This applies to 1-4 unit properties.

(you spelled loan wrong, though applying for a loan is a very lonely process sometimes)
