We're going to have to do some upgrades to the unit to get the next set of tenants so we're currently saving up to be able to do that before we stop renewing their lease.

Look at the actual cost of the renewable energy.

It's getting close to the lease renewal period for the tenants in my property, and I'd like to be prepared.  

Incidentally I just got my renewal and with more units it is now $23/door/month.

I think you also have to renew your interest in the lien each year, meaning someone can buy it out from you if you don't keep it current.check out the BP Podcast #56 there is a lot of info on Tax Liens in there.Hope this helps man, Im just regurgitating what I've kind of picked up, so sorry if Im incorrect!!

I am assuming you can renew it upon expiration for roughly similar terms. 

We signed a lease the first year and the lease stated that after a year it could be renewed or you could go month to month with a 10% increase.  

EVERY surface in the home is replaced/renewed... please explain to me how it would be possible for contamination to remain?

If I were to close in say 2 months, could I do a non renewal on one and move in 5 months after closing?
