At this point, I would recommend having a line of credit to cover these things so you don't have money sitting in the bank doing nothing when it could be put to work.I have 33 units, no debt except for mortgages, and excellent income.

Are there any strategies here to utilize bank funds for our project?

Many community banks will give you credit for proforma rents.  

Raising money is all about marketing and sales (not real estate specific) so either hire marketing agency and read sales books, or hop on some LinkedIn courses on marketing and sales.Not sure the legal structure to use: talk to accountants and attorneys.Need deal flow: talk to brokers and go to a lot of networking events.Lending terms: start calling banks and loan brokers.From there, it is all risk mitigation. 

Just like a bank tells you what the terms are, not you as the buyer.

I walked to the house and met a man who says he was cleaning out due to the loss of their mother in some few weeks back.The guy told me she is  left with 12 years mortgage on the property to pay the bank.

. - PM provides a cash based accounting report every month, for every unit under management, that clearly labels all rent, all expenses, including management fees, and the net directly ties to the amount of money deposited into my bank account.- PM is a licensed handyman, or has them on staff, and takes care of most unit turn work at a reasonable rate. - PM has no breakup/termination fee- PM does not take project management fees, except on large or complicated CapEx projects exceeding $5,000. 

Any local bank that does this kind of financing should be able to approve you as long as you have a good enough credit score and never declared BK.

The value of your SDIRA may be too low, but I'd recommend Gary Mobbs at South Star Bank in Gonzales, TX.

Yoru bank probably wants yoru mailing address to match your ID.
