I'd say a few hundred dollars for half a days' work.

You do not need to give a specific reason for doing this, just let them know that at the end of x month that they will no longer be able to live there....However, if this tenant has been; long term, hassle free, and prompt with their payments, maybe you need to reconsider moving them out as you may find the loss in this cash flow to put a hurt on your income.I would say a good compromise would be to see if the tenants want to upgrade to the bigger unit, where you being the kind landlord offer a "reduced" price to them.Ultimately it is your decision, but be sure that your decision is not based on emotions but rather simple dollars and sense. 

steve Vaughan   yes lots of questions and no answers.. probably swamped with off line PM questions and answers That may be, Jay, but wouldn't you take a sec and say as much?  

Say a property returns 10% cash on cash, which to some, may be low.Said property's tax rate is 2.5% purchased at $200k or $5,000 for property tax.

@Galen Ikonomov - what would you say as to why you WILL not email it to her?

However, it should in theory tax the somewhat wealthy (say...a little less than a million in equity) more than the super wealthy and thus would be somewhat regressive.Thoughts?

I don't know what the legalities are, but I would certainly accept an email as, say, a 30 day "written" notice from a tenant that they don't intend to renew, or as a written request for maintenance issue.I wouldn't use it as a notice to vacate or indeed anything that could potentially turn confrontational.

Or say a tenant moves out and you have another who wants to move in but has different space requirements and you need to divide the space, or you need to do foundation work to install heavy machines, etc?

On the other hand if you invest into a multifamily property via say a partnership, there is no similar pressure to sell within a time period.

Caveat: Some states say a late fee cannot be applied until a certain date, while others state that rent cannot be considered late until a certain date.
