That's a low-return improvement, compared to say new bathrooms/kitchens.IMHO, if you expect to increase your net through rental and market appreciation, consider the length of time it will take to realize that goal—many years. 

Purchase price: $190,000 Cash invested: $69,225 Contributors: Taz Zettergren, Chris Clothier This home features 3 bedrooms, 2 bathrooms, a driveway, 1,140 sq. ft., and a single-family detached garage, built in 1989.

Also are currently turning a Jack-and-Jill bathroom into two bathrooms, to add value.

The guest bathroom could use a little updating.

This included updating the kitchen and bathrooms, improving the landscaping, and finishing the basement to maximize rental potential.

The property is 3B1B and I plan to add an extra bathroom it 3B2B.

If you can find one with 2 bathrooms that is ideal.

Try looking into zillow/Redfin and see what your potential rents you can get near the neighborhood by filtering the bedrooms/bathrooms of the intentional property that you are planning to buy.

I added value by renovating the kitchen and bathrooms, updating the landscaping, and finishing the basement.
