Many do not allow it due to the city wanting to focus more on higher-priced real estate asset classes such as single-family homes, apartment buildings, etc. 

But there is a huge secondary mortgage market out there, most just do not know about it.Whole Loan Sales | Fannie MaeBasics of Single-Family MBS (fanniemae.com)

Hi, I am new to Bigger Pockets and I am looking for my first single family long term rental deal.

Investment Info:Single-family residence buy & hold investment.

However, there are also single family properties that can offer great returns as well.As for navigating buying a duplex with tenants, it's important to do your due diligence and review the current lease agreements to see if they will fit your plans as a landlord.

My company works with Insurance Adjusters, as a third party, to find short term leases for local families who have lost their homes due to damages.

On the professional side, I provide annual net worth statement updates to the families I serve. 

This would be my first multi family investment opportunity, and If it goes the way I’d like, I can purchase 2 more duplex’s from the same owner.

I am looking to be a passive investor in a multi-family syndication.

Banks don’t like that, nor for resale.Realize this property is part of your family history, but would have an Immobiliarie research the property and identify all issues and give a repair estimate before digging deeper into this.
