I eventually want to improve/add value and develop real estate as I gain more experience and connections in the industry.

If you decide to go the mortgage broker way and are successful, you will develop a solid relationship as well. 

I have 3 adjacent properties in the Los Angeles that are going to be in an Opportunity Zone.One thing I cant find is how to go about finding funding from Opportunity Funds if I want to re-develop the land.

I am considering doing a 1031 exchange for two properties (1) a SFR ($230Kish) I will turn to a shor term rental (STR) and (2) about 27 acres ($200K) of raw timber land I would subdivide and develop into more SFR-STRs within the next three years. 

Has anyone had experience with a Boston-region prefab building company for multi-family development?

As for Zoning, I gave a call to my friendly town development team today and they were extremely nice and helpful.

Investing defined:  expend money with the expectation of achieving a profit or material result by putting it into financial schemes, shares, or property, or by using it to develop a commercial venture.  

I've spoken to a few sellers with enough equity to develop a relationship but some of these FSBOs are smart.

Who knows what they'll damage next when maybe you could've given them cash for keys beforehand.Also, you need to pull prospective tenants' credit reports & do background checks, including calling their employer at a phone number you get from the company website.

We may take on more debt if the value is there, but some of the most sage advice I ever received was from a long-time real estate developer:  "Have a plan to hang on to your property at least a decade."
