Add a second bathroom in second floor master?

[Roy Gutierrez]

Hello,

I bought a bungalow in a middle class neighborhood in Michigan, centrally located and close to a very nice downtown (not detroit!) but the house is in the service drive of a highway, it's a pain to back out into the service drive (although could turn the car around by going into the grass area at the back of the house), that's why I got it cheaper than other houses in the area, 29K and putting about 20K in renovations. I'm renovating the entire first floor which has 2 bedrooms, brand new bathroom and brand new kitchen, the master bedroom is in the second floor and it's not bad so I'm leaving it alone. Houses in the area compared to mine are renting around $1,000 per month, so the cons are my property is in a service drive, no basement, and no central air (no biggie in michigan but being on a service drive and considering car fumes might have to install one) pros are most houses won't be as nice as mine, renovated, nice open layout and 2 car garage.

Now to the question, I'm concerned that the master has no bathroom, so the renter will have to go downstairs to use the bathroom. How big of a deterrent would this be for a renter? Could it be worth it to add a bathroom in the second floor? I estimate it will cost me about $4,000 to put a small bathroom.

Thanks for the feedback in advance!
