I got a couple of companies to give me quotes on the commercial property, then I chose one (American Family) they went out to take pictures of it an noticed some mildew on the back,and the AC's were missing.

I have read all the Colorado statues and annotations, and can't find anything suggesting I can't keep endorsing/let interest accrue past the 3 years time.So my question is, if your tax lien is a small percentage of property value, why would you bother to start the redemption process and most likely get your capital back? 

But just as you're trusting the tenant to make payments on time an not default, you're also depending on the seller to do the same.Its really no different than a traditional rental situation.

I an NOT giving you advice.  

if still decide to send a physical lease you canuse post it stickers to annotate areas that need signatures and initialsorinclude a separate checklist of each of the sections.  

The hotel manager was able to annotate that any other fees were the tenants responsibly.

Borrowing against an asset is allowed as long as the payment is annotated since that payment is required to be paid back by you. 

I would highly urge you to read and annotate it!

However as I still do work a day job, I an not quite at the point where I can start taking Random Phone calls from the general public, which makes Driving for Dollars, and mail campaigns challenging to field leads (Phone Calls) in the middle of the work day.This is where I need to start playing to my strengths. 

@Suchi Desai, if the addition is not annotated on the tax record, it is likely the work was not permitted.
