I have a few properties and am also a mortgage broker, happy to answer any questions about general investing or financing options.

Was focused a lot on being a realtor have brokered 50 million now but if knew they would appreciate so much probably would have just focused on buying more myself.

In south Florida, there are a ton of free RE networking events where contractors, agents, mortgage brokers, etc all meet for drinks etc and I have found this to be a great way to find good people in the business.

Quote from @Patrick Shep: I haven't had any brokers ask about students as renters.  

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

In Ohio we just consider wholesaling brokering real estate.

Just make sure you take your policy to the brokers so they can do a direct comparison.Maybe hit up your primary home insurer to see if they offer a STR policy.

I’m a broker based in Charlotte, NC, and I work with Compass to support investors in maximizing their growth strategies.

What would people recommend I pursue, commercial or residential broker? 

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.
