If you look on the county web site they should have info on when they're due.

I have a web page set up that tells the entire story.

BP imo possesses the most REI based intellectual resources I've seen since I began my web surfing back in '93'.

I work in a lot of digital spaces with web and marketing projects.

Allows multiple payments for rent, allows for maintenance requests but does not auto notify selected vendors like Rentigo (that is a nice feature); text when tenant pays and when money is deposited.CONS:  not able to set up late fees; no mobile app (but web site is mobile friendly)Right now they both have +'s and -'s, but the lead right now goes to Cozy only because I have all the money in my account which is very important to this business.  

The City and County of Denver has a pretty good web page on the process if I remember right.

In the Results link click on your address where there are various tabs and click on Neighborhood Sales.If you have a hard time with technology, you can always ask friends or family members to help you navigate the web to do some research about property values in your area.If you do find yourself entertaining an offer from an unsolicited investor:Ask to obtain, and keep, a list of the comparable property sales in your neighborhood the investor used to come up with their purchase price offer.Always keep someone else in the loop – your children, good friends, or someone you trust.Always know that you can seek legal advice – in the end, it might be worth the money you spend on a consultation with an attorney.Review the contract closely to see if it is assignable.

In CO you can do it on  the secretary of state's web site. 

But what else can the web do for wholesalers?

No clue if the 3-day program is good or not but I would rather read books from the library, surf the web and learn from mentors.
