But somebody could use a credit card fund the immediate need and then pay it back with the policy loan fairly quickly.

I'm wondering if a BLOC could help to build my business credit.

Usually the numbers don't work to build in these neighborhoods, unless government tax credits, etc.Do you see the problem with your two statements:"The turnover costs could/will be high"and"How much more damage could they do?"

I don't take credit cards but I believe stripe does.   

Specifically, I am looking at partnering with an individual who owns securities (stock and mutual funds) having them take out a line of credit against their portfolio (SBLOC) at a low interest rate, and using that to purchase properties rather than using a mortgage.

Another work around that isn’t discussed much is working on a strategy with your insurance company to protect your other assets in the event of a claim.But also, it wouldn’t be a bad idea to consider getting the financing into your LLc name with a community bank and pulling cash out if you have substantial equity.Right now, since the loan is in your name, it shows up on your personal credit report.
