But really all you have to do is notice the tenant that their rent is being moved closer to market rate.

Doesn't seem like a smart ROI move for Fanny Mae, in my opinion. 

This is a desperation move.

I am open to other scenarios.We have access to $200k ish in equity in our primary.We will soon have access to another $100-150k for retirement/investing/IBC/etc.I would like to move into my young family into a (new build or fully renovated side by side) duplex.

In general, my personal preferece is to move all of my properties to management.

If it's well written and well documented, this will take <2 minutes for every loan you do and solve your problem moving forward. 2.

I don't want to get stuck trying to rent out the house in winter months (upstate NY and no one wants to move in winter) but also don't want the tenants to have to leave until they are ready.

We are in the process of finding  a HM lender to finance  a lot and spec build.We have a lot that we want to purchase and already have the plans and have built this house numerous times already.One lender is asking to have a permit issued before they move forward.

If my spouse was not so averse to the idea I would move once a year to new multi family properties taking advantage of low down payments.

What can I expect moving forward?
