If approved, do not process any additional apps, BUT, you can certainly hold onto them as backups until you actually collect the full SD and the first period rent (whether pro-rated or full month).

Depends on what you back up against.

Experience, $$$ backup, other units etc.This isn't something I would consider.

I was told it usually takes 14 days but due to back up on appraisers the time line could be upwards of 30 days.

Doing a partnership with someone you don't know that is already looking at back up plans may not end well. 

They are WiFi enabled battery backup and locked and unlocked with a smart phone.

I use a shower caddy for the tenant to have a soap dish and shelf for shampoo and such.I've actually been able to remove them when I've had to get at the plumbing and, after cleaning the old glue of the back, glue them back up.

Not all will be cash buyers but it is a quick back up option.Also check public records: A house has two primary documents.

We actually keep marketing your property and accepting back up applicants until your property is actually occupied.

They sync without Hospitable just fine (I use Hospitable and they advised me to sync Airbnb and VRBO iCals as a backup).
