*Credit is low to mid 600s due to high credit utilization as a result of covid.

Are you preapproved for a working line of credit?  

Share your tips and tactics for negotiating favorable terms, including price, contingencies, repairs, and closing timelines.

Maybe personal loan from a bank or credit union, friends and family.

You can always complete a line of credit or cash out refinance and repurpose that equity while keeping the asset (all tax free money). 

We do however run a credit report on the guarantor(s). 

Pair that with a great credit score and you'll see rates in the mid to high 6's (assuming DSCR loans).

From multiple discussions I've had and reading posts here, I think I also want to form a 5th LLC to act as a management company, so that I can have one business account and credit card to collect all rent and pay all the overhead and expenses (paying for meals, PO box, RE licensing fees, etc).  

There are low money down options for people without experience, but you'd usually need good credit.

What is your credit score?
