I would reach out to a local environmental engineering company to discuss what you are wishing to do. 

I'm always happy to chat REI locally, and would encourage you to come to the next meetup -- second Wednesday of the month at Pearl Street Grill & Bar downtown.

I would check on Eventbrite & Facebook for your local events! 

Educate yourself on the local market, network with other investors and agents, and always have a solid plan in place before making any investments.

Post the city your property/idea are in and network here on who we use on the local market4.

I bought the properties from another local investor and would like to get a hard money loan for the rehab. 

Attend a local meetup that attracts different investors.

But reach out locally and see if there's any option at all.

Reduced down payments are possible for multifamily buildings using financing options such as FHA loans, which are less expensive than traditional loans.Find local programs that can help with a down payment, look up programs in your region, get in touch with lenders or mortgage brokers in your area, and fulfill the eligibility requirements by attending homebuyer education workshops.

My suggestion  for you is to join some local REIA and find contractors there.
