I'm currently interested in raising a fund to buy multifamily apartments.

Without question, do not open escrow or transfer funds without going through a Real Estate Law Firm. 

Low salary, low on funds, low on knowledge.

Besides what you've mentioned, here are a few additional common expenses to consider:Landscaping (especially if there’s grass or common outdoor areas)Pest control (sometimes needed for multi-family properties)Legal/accounting fees (for lease updates, tax filing, etc.)Vacancy reserves (for covering costs during turnover)I can assist in helping you find funding, LMK! 

Hi,I would like to connect with anyone who has experience in EB5 funding of projects. 

After all PITI, utility, and services (lawncare and cleaning) costs I have $7,225.I set aside 25% of this for my maintenance fund.The remainder funds my lifestyle, wife has a Tesla, and quarterly vacations as well as business growth.In 2023 I am tracking to build 4 duplex units designed as room rentals funded in part from a recent land sale.

So depending on when you're looking to use the funds a fixed might make more sense. 

Can he just wire the funds to escrow, I sign the deed of trust, and that's that?

This property can be refinanced at any time you feel is right after the 1031 exchange is complete to buy other property or access funds for any reason.  

As for capital, I will be utilizing my HELOC for initial fund on first deal.
