We are going to renovate one unit right away with new carpet, new paint, and a bathroom update.

This is how I learned to paint, plaster repair and install light fixtures.

Later we sealed gutters, repaired masonry stucco, added exterior paint, porch deck, and replaced half the windows. 3 units were totally upgraded inside inc@luding floor refinish, and paint. 4th unit in progress.

We repainted the outside of the home and cleaned up and painted parts of the inside of the home.

Snow removal, mowing, painting, etc.
