I think a kind reminder telling them that they are not allowed to use the agent or lender finder to solicit business and if they don't get it the first time, a simple temporary ban will help stop this. 

I just had my first tenants move into my property on the 1st, when doing the final walkthrough I reminded them that there is no garbage disposal in the kitchen, I did mention this to them before they signed the lease.

Use a CRM to save everyone's contact info, set reminders for yourself to follow-up, create follow-up campaigns, etc.5.

Thanks for your reminder.

Another reason to send it by mail is in many cases you will be deducting damages from deposit.  

A simple phone call or e mail  Hey you sold my friends house they loved you would you come to our house and help us like you did them.My wife got one yesterday daughter of one of her clients.. she has a 600k house to sell and wants to buy a 750k house ..

Our situations are also a great reminder that someone has always had it worse, and there is a lot to be grateful for if we look at the situation the right way!

Hi There - We have had several clients make the numbers work here in Chicago typically with either FHA 203k and home style renovation loans.I continue to remind everyone that a single or walk right now will be a double, triple, or even a home run down the road. 

They have an app, scan your mail, forward mail, and will even deposit checks (forward/mail to your bank).

I have to remind myself from time to time.. you did a good job breaking it  down.
