Not sure what you mean at 2.75%, current rates probably around 7% depending on your credit and down payment.So you own a home now and looking to rent that one and move to a owner/occupied 2-3-4plex?

As with most things, the answer is it depends.If you had the right mentor or coach, it could potentially move you forward in a big kind of way.

I am looking for advice and ideas on a home I have that is a zoned business.It is two lots separated by a shared private road.

I'll need to make some renovations like finish my basement so I can make use of that as well and move laundry to a more central and convenient spot so it can be shared.

One tenant is moving out March 1, so i could give other one notice now they on month to month, or just have them be there for carrying costs.

Since then however, I’ve learned that it’s best to keep life insurance and investments separate.  

Long term tenant moves out this summer.

Can I give a tenant written 30 day notice on June 1 (in person or taped to the door) for move-out on June 30? 

You will need that anyways for a lender to move forward. 

That's a great move.
