gracefully end lease with good tenant

[Brent Rieman]

Im considering not offering a lease renewal with a good tenant.  The tenant has been in place since before I purchased the building 3 years ago.  They have been great, accommodating, pay ontime and have only caused me a little headache.   You may wonder what sane person would do this.  Well were getting ready to do a large renovation on our house and will need a place to live for 5-6 months.  This is the unit in my building(8units townhouse style) that, 

1- has a lease ending in the timeframe we need,
2-is most desirable unit in the building, its a larger end unit with alot of privacy. 

I have alot been kicking around the idea of turning one of the end units into a short term rental and after we move back into our renovated house, this would the perfect unit to do that with.   I have been very accommodating with the tenant over the years, they have had some health issues and have continually asked for 3 - 6 month lease's.  The conscience in me says dont be a d!$k but on the flip side, this my property, I put myself and my family through tons of stress and late night projects to purchase and own it, and if this it what I need from it why shouldn't I.
