Yishi Zuo, I understand your desire for collateral.

@Wil Reichard It seems the asset/collateral is the issue here, not the amount you have invested.

Essentially no income details are required and the loan is based off of the collateral of the property and income, calculated using the active rents, appraisal rent schedule or even STR income or projected income.

Talk with your current lender and cross collateralize the existing properties with the new property.  

I did pledge assets to cross collateralize.

But since private money is relational based versus purely collateral based, you'll need a track record to prove yourself.

Ideally, if they have other properties, getting collateral on that as well. 

The only way I thought I could protect myself better in this situation if I were to decide to move forward would be to cross collateralize by taking a first lien on a separate property of the borrower.

Theoretically, we can then attach the funds to a new property or a temporary escrow account through an already agreed upon "substitution of collateral."

If you want to use this as collateral for future deals, you will need to finance out of the SBA loan later, or put more money down on a conventional loan 5 year term/20 year amort up front.B.
