Think of it this way:
If you worked hard at setting yourself apart from the rest to finally get that person to take interest in you and then stopped giving them the same attention, do you think you’ll still have the same relationship with that person?
Heck to the no. They’re going to be telling you peace out.
The same concept applies because, in the end, it costs you more to find a new tenant than to keep them. It's still takes work, but making sure you listen to your tenants' gives you a win-win situation.
