The courts will handle service via e-mail and delivery to the unit.

Send the tenant a notice of declination in writing; send by email and then in writing through the postal system with proof of delivery required. 

Send a written notice (yes, paper) to the tenants with proof of delivery required (the postal carriers have this time to an art form; it's inexpensive and you get confirmation via email or receipt very quickly; it does not require the tenant to sign - it just confirms that the notice was delivered.A paying, respectful tenant is golden.

Send the notice by Certified Mail AND a separate mailing with 'proof of delivery required' (a cheap date with the post office).Hope this helps.  

The Notice needs to be sent to each tenant by both proof of delivery required service from the post office as well as by certified mail to the last known address.

Also know where your local laundromat is and what the pickup/delivery service is.

Once they delay on the deliveries. started, I stoped selling and offering properties for sale from d32.

If there are changes you want to make then send your tenants official notice of those changes via in person delivery or certified and regular mail along with a copy of the new lease.

Example: If a business buys an oven and it costs $5,000, and $1,000 for installation and setup, and $200 of delivery and transport fee. 

Existing deals will instead be saved by NOI growth driven by rent growth--if you have the staying power to hold on long enough.Supply:  High deliveries remain today mostly because of "hang over" from projects that are taking longer to complete than developers (and industry analysts) expected.
