Bridging a funding gap in situations like this can be challenging, but there are several strategies you might consider:Bridge Loans: Short-term bridge loans can provide immediate capital to cover the funding gap until your other funds become available.

I have looked into multiple "Angel Investor" sites (invstr.com, pitchbook, askforfunding) as our company is growing and we need to secure funding before we turn loans away.

If you have a loan, you may wish to look into due-on-transfer clauses.

I used a conventional loan to secure the property.

This can lead to missed opportunities, especially when speed and flexibility are crucial.Personally, I’ve seen investors switch to creative or alternative financing options, like hard money loans, private lending, or even seller financing, to avoid some of these pitfalls.

Current plan is to take out an equity loan on the property (tax rolls have it at ~$300k) and use some additional cash to build 4 units, then refi, then build additional units until we have ~20 doors on the property. 

Also, the LLC does NOT eliminate any personal liability on the next loan application which is a popular selling point by ill informed DSCR brokers on this board (but they rarely mention the higher financing costs that come with financing in a LLC) IMO, proper insurance coverage is a better choice. 

While we can't assist on the down payment side, we can help with the loans.

This will set you up to get future loans.
