Go through a broker.

Talk to a mortgage broker or lender experienced with LLC-owned properties before transferring ownership.

As we wrap up the year and look ahead to 2025, the real estate market continues to present unique challenges and opportunities for investors, brokers, and lenders alike.

Do you work with Brokers? 

Meet with a local banker & schedule a time to talk with a mortgage broker, they'll give you at least a baseline of what kind of down payment options and rates are out there.After that, if you're still wanting to research more creative options, do some looking into seller financing (a very hot topic with good, and bad, advice out there), look into private lenders, and commercial financing options.If you're wanting to live in 1/4 of your quadplex, then conventional residential loans may in fact be your best option as you can purchase that with a fannie/freddy loan with very low down, and use up to 75% of the income from the property toward your own income. 

I tried to work with Digb and they provided some of the worst customer service I ever experience.

You're running a business and businesses choose what payment methods are acceptable to them - not the customer. 

Quote from @Briley Roe:  yes those fees are very high as you have a broker fee and other fees for a loan little over $100k at 6+ points.
