These include traditional rehabs to sophisticated market specific value adds.

Unfortunately as a part-time agent, you also likely won’t get that support you need from a traditional brokerage if you’re not in the office on a regular basis.

Tried to go the traditional HELOC route and after almost 2 months of providing paperwork the lending scenario changed (due to rising rates) and they backed out. 

The disadvantage is that the indoor units are a bit large but if you place them nicely they'll blend in to any room.Another advantage is the upfront costs are much less than a traditional AC system.

@Adah N. starting at around 10% on investment properties but they fund you the full amount immediately, so it’s not exactly like a traditional HELOC where you use it when you need it.

It’s a matter of cash out refi vs. traditional refi. 

Funding can definitely be a challenge for first-time flippers, especially when traditional lenders are hesitant to take a chance.

However, if you plan to rehab at all, you will then need a licensed contractor to provide bids on each project you plan to rehab.You will then be asked to provide a proof of any funds to close, purchase agreements, and if closing as an LLC - most times documentation on that LLC.Overall, the larger number of units (5+) makes the lending process based more off the property than the borrower, contrary to traditional single family housing.I would recommend you work with a Loan Originator/Broker who will be the medium for you to the lender/s.

With rates as they currently are, I'm looking for every angle to get the lowest rate possible, and from what I understand, credit unions can offer rates slightly lower than traditional banks. 

Most will double charge on all fees for double closings which can make them thousands more than a traditional closing.
