A good positive letter with an invitation to meet face to face and your contact information, as well as a token gift ($5 gift card to starbucks or something home-y), should leave your tenants with a great opinion of you and will hopefully encourage them to give you and your new units the same respect you'll be giving them. 

Thanks .................for the encouragement 

Hi David O,Thank you for the advice and encouragement.

Be encouraged!

They incorporate a secondary heat exchanger (much like an Evaporators A-Coil) that has less space between the fins.

It always helps you to stay ahead of competition and encourage long-term tenancy.

Thanks so much Brett for the encouragement!

Ill keep you posted@Joseph Lanzotundefined - Thank you for the encouragement.

@Brian C.I'd encourage you to a) save up more or b) build up your business more before you go full time.I worked full time at one company for years while I built my real estate business.

Nothing wrong with offering a higher BAC as a FBSO to encourage them to work with you, I didn't mean that you'd be paying them to rep you in contracts - that would be bad advice.
