If your ROI is greater than 8.75% and you have cash reserves to offset the decrease in liquidity, go aggressive and keep expanding (if allowed by the bank).  

This would greatly decrease the  number of no-shows (if they had already taken the time to complete an application they are likely very serious).A handful of our users are doing that since the application is online and can be completed in a few minutes.

The rates have decreased .375-.625% depending on the loan product and apply to rental investment property such as single family homes, condominium units, 2-4 units, and multi-family.

This should decrease the odds of being a bad deal.
