However, they do have 11years of investment experience under their belt (100's of multi-family rentals, flips, etc) Would this individual have any options for financing more multi-family? 

Hi Tomoko,I wouldn't focus so much on the license that an individual has but instead their knowledge and expertise in your specific field of work, especially for real estate.

If a cash out refinance, many lenders will allow the cash out to satisfy the reserves requirement.DSCR lenders generally let you vest either individually or as an LLC.

This is an internal accounting requirement  You can cut a check to any member as a drawing or return of capital, to them individually, that's not an issue. 

Instead of spending money on education which is available for free, I would attend REI meetings, conferences organized by real estate guys radio, Joe Fairless, crowd converge, New Orleans investment conference etc to network and meet like minded individuals.

Currently, I am in the process of negotiating another commercial building and an additional industrial warehouse adjacent to my initial investment.Looking forward to connecting with like-minded individuals and exploring potential synergies.

This marks a departure from the previous multiunit financing requirement of 15-25% down payments for duplexes, triplexes, and four-plexes.This new option presents a great opportunity for individuals looking to invest in multifamily homes while also enjoying the benefits of homeownership.

Unless you can come to terms with this individual; eviction might be the only route, and that might be a tricky process with someone who "knows their rights" my buddy recently had an issue with this, and it took him over a year to remove the tenant.

DSCR loans seasoning period depends on the individual program (and there are hundreds with slight differences).

Search the lender for deeds of trusts and you'll see if they do business.BTW, any entity that offers or requires a participation in profits that is a lender is looking for trouble, this type of deal should not be made from the position as a lender but as an investor through a non-lending entity or individually.
