You need to build relationships with corporations.

I also found the local DoorDash drivers and built relationships with them to help my guests in time of need.

I'd suggest finding the top sub-institutional brokers, building relationships with them, and letting them know what you're looking for.

Remember that having a good relationship with a lender is more important than a small difference in interest rate (In my opinion.)Cheers!

Many agents claim they can handle multifamily, but working with one who owns similar properties provides better confidence that they know what they are working with.However, if you are looking for larger multifamily properties—which are not listed on the MLS—it’s essential to build relationships with those brokers, as they often don’t list these properties on central services.

In summary, an ejectment seems far more burdensome for the Landlord/property owner than a eviction in a typical landlord/tenant relationship. 

If you’re not yet married I would recommend a partnership agreement that spells out your agreed upon exit strategies in the event that things go wrong with the investment or your relationship.
