You might also be a good candidate for a small boutique hotel, an operator looking to retire will often entertain seller financing on fair terms and you could likely qualify for a SBA loan to help with your vision. 

Our mortgage rate is 3.9 so I dont want to sell the house and instead hold it for the long haul.

It might be easier to treat it as a full scenario with Purchase price, Down payment, Term, Prorgam, occupany, number of units/rents per door, Taxes/Insurance (Any flood, HOA) etc. 

Is there a standard letter that I need to send tenants a month before the end of their lease to remind them to move out by the end of the term?

I realize I'll need to look at zoning, put together a site plan, etc. to know exactly what's possible in terms of how many units can fit on the site.

I have some good folks now but it took a very long to put a good team together. 

Hey all,Long time follower.

. - These are the two channels where these companies will seek out listings for their housing requests.Longer term you should be networking with businesses in the area that are known for having housing needs for their employees.

Both were converted from large SFH to multi family a long time ago.

. - in this case, I will have more time to shop around for better loan terms/rates etc.
