Is there a way to start your real estate portfolio or a business without having collateral or mixing personal finance’s?

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

I'm not bold enough to buy real estate at negative leverage - few deals in my area (and I presume, Manhattan), are trading at "Cap Rates" greater than 7%. 

Do you have any other real estate you can borrow against?

If you own real estate in your own account and are just building wealth to pass on to your heirs, it works great. 

I'm a real estate agent and investor. 

Focus on maximizing your W2 income over a real estate market.

A good local realtor will be able to guide you on the neighborhoods and should have deals available to you that aren't being listed to the open market. keep in mind intel facility is going to be a slow roll given the state of the company.. its not going to be like the intel fab in Oregon and Arizona that created massive RE opportunities

Isnt real estate awesome :D 

Title insurance does not represent the status of title to real property, and an insured cannot rely on the title policy to represent the title.
