Converting living space to bedroom, can I advertise as a bonus room?

[Mike Jones]

Hello,

I'm flipping a small 1 bedroom, 1 bathroom house and I can easily wall off some of that space to make it into a room.

Would this add much value to the property and can I advertise it as a 1/1 with a bonus room?

I dont want to go through the permit process since I need to sell this fast due to divorce.

Thanks!
