I like the fact I can do this online. But, being new, it's complicated finding my way around. I cannot figure out why the font changes size when completing column J - both lines.

As a landlord in a 2-family house, it's easy to create a lease. However, it's impossible to alter standard terms and conditions - this is a drawback.

Great program a fairly easy to use Great program a fairly easy to use. We had to cancel because my company could not justify the expense of the program at this time.

Smooth fillable process Smooth fillable process. It's just the end of the process, saving the document and accessing it that I still need to get used to. I don't feel too comfortable as I feel like my documents are not easily accessible if I forget my password. I guess it's a matter of getting used to. Also is there a charge sometime in the future for this?
