Many times it's stated in the lease as a reminder.

I haven't forgot about those forms so just send me your contact info and I will remind you everytime I see one of your postings.

It is a very simple answer and my Realtor still reminds me from time to time.We as wholesalers do not sell Real Estate, we sell contracts.

Ask the seller to pay for the repair or lower the sale price or pay for closing...remind them that if they pay for closing they get a tax credit.  

This also reminds me of one of my favorite childhood shows...."

When I noticed I was still receiving bills for the trash and sewer service in my name (the service is provided by the city), I kindly reminded him to change the service into his name and take care of the bill. 

@Ryland Taniguchi Your post reminded me of a phrase I recently heard - "Communist Republic of California" lol. 

They are a little pricey at $3 per transaction but you can setup payment reminders and automatic late fees.

I probably wouldn't do the gift card thing but if they were good tenants throughout the term of the lease, well then when it cam time to raise rents I would either leave their rent as is or slightly increase it while also reminding them that you really appreciate them as tenants and this is your way of showing gratitude. 

I guess this is a good reminder for all of us - tenant turnover or once per year check the ac drain line for clogs.
