Quote from @Brandon Croucier: The loans are available but nobody wants to do them.There always seems to be something wrong with the properties, as lenders we just can't make enough $ for our time.9/10 Borrowers also complain about the "excessive fees" for the loan amount.If you are okay with paying 8k in closing costs then the loan is available. 

We are in Los Angeles, and although we do not own anything in SD, we hold a loan on a portfolio of SFR's there that is not performing at the moment.

typically no special license is needed when doing it for hard money loans that I am aware of. there may be states like california and nevada that are tricky where lenders need a license of some sort but for most part brokers i have seen are not licensed. 14 or 15 states require state license and NMLS registration.

Option 1: The loan that the owner has is an assumable loan at a 3.875% rate and still has about $265K.

Are you looking for better loan terms from the lender?

Once construction is complete you could refinance out of the construction loan into a DSCR loan.

You would need to let them know you are 2nd lender and want to pay the loan off.

Quote from @Arshiya Taami: I am planning on purchasing a profitable business with its real estate included in florida and the dscr is 1.85. the problem is im just short of 600k for the down payment. that being said, can anyone provide me any reputable loan companies that will offer bridge loans and what their requirements are. thank you in advance! 

I've been investing in loans on Equity Multiple, which is a commercial RE crowdfunding site.

Start by talking to a bank/loan officer to see how much you can borrow.
