To rent out to students, I am planning to convert a spacious family room and a dining room into two additional rooms. 

The house is spacious and I enjoyed having good renters around whom bring in cashflow.

Full kitchen with breakfast nook, spacious deck, and off-street parking.

Upstairs: Spacious master bedroom w/ double trey ceiling & his/her walk-in closets, Master bath What made you interested in investing in this type of deal?

This is a spacious 1 bed 1 bath, and I am looking to turn this into a 2 bed 1 bath.

I want to add a 4th bedroom in a spacious unfinished basement however I have herd that there are restrictions.

Interior features include 9-foot ceilings, eat-in kitchens with Energy Star rated Kenmore stainless-steel appliances, spacious pantries, granite or quartz countertops with undermounted sinks and premium Kohler plumbing fixtures, custom cabinets, in-suite full-size washer/dryers.

Both the upper and lower apartments feature an open living room and kitchen, 3 private bedroo, 2 full baths & spacious laundry rooms.

Would it be feasible to market it as a " 4-bedroom, 4 bath PLUS spacious office AND a bonus room" or words to that effect?

For a smaller unit, appearance is going to be more important than for a larger unit in that it feels spacious.
