Looking for 36 Washer/Dryer Combo units.

[Karen Trezza]

Hello, I have 36 one bedroom units and I am looking to enhance my rental income by installing a washer/dryer combo appliance in each of the units. 

My question is:  is there any way to get bulk pricing and how would I go about getting it? 

Also, what should my rent increase be with the current rents at $575 each?  I am considering increasing the rent for water and convenience sake to $635.  Anyone who has one bedroom units knows you can only charge so much and go so far on increases.  I am doing cosmetic upgrades also so that the tenants see improvements.
