Advertise like you normally do that the house has 2 beds/1ba (or whatever the configuration is). 

Use Full size Washer/Dryer configurations.

Or change the unit configuration to a two bedroom and a one bedroom by eliminating a kitchen and changing to a bath.  

Our major building configurations will be 30 foot wide buildings, so we compete with a 15/15 or 10/20 unit configuration.

It probably will not be desirable next to your kitchen, depending on the configuration.

What @Russell Brazil is alluding too is that you might want to consider converting it back to a 5/3 to get your loan and if you really want to walk the hairy edge or what may or may not be legal, convert it back to your 4/3+ configuration later.

I'm working on designing my next project and need some advice on the configuration.

Ultimately, we did change the configuration of the main hallway and master bath to allow for a "true" master bath (this was a 70s split-level with a very modest master bath originally) which I believed was crucial to getting a higher sale price.

One change-in-scope to original plan was renovating the hallway and master bath configuration.

Is your priority to have a ton of features or would you rather have super simple to setup and use so that you can focus on doing deals rather than configuring software?
