The duplex next door burned down at some point somewhat recently and insurance replaced all the siding on that side of the house.I’d like to make it a 4/2 or at least add a half bath, but it would depend on where else the money is eaten up.

Having a separate bath was viewed as a convenience, particularly for the help. 

You will also likely need street/sidewalk closure permits at different points in the jobUtility Taps- Water, Sprinkler, Sewer, Power, Gas, Cable (this is likely negligible as the cable company should do it for you)Excavation/Foundation- Are there buildings on either side?

I kept in touch with the seller and ended up buying three more duplexes on the same street from him over the next two years. 5 years after that, he passed away and his estate contacted me to see if I was interested in the rest of his holdings in the neighborhood.

Addicts and prostitutes would be walking the streets after it got dark.4.

Each unit is a two bedroom 1 bath and they rent for $600 dollars a month.

He played the big shot moneyman right up until a week later, when I found him naked in bed with his furry privates out, high as a kite on some kind of smack, blubbering his eyes out over a 400-lb equally naked woman who had just been brought back from death's door with Narcan by paramedics from the three ambulances and five cop cars blocking up the street my duplex is on."

Each side is 3 bed, 2 bath, 2 story, 2 car attached garage.

Purchase price: $255,000 Cash invested: $52,500This is a duplex that my wife and I found, and are currently living in while renting out the other half. 3 bed, 2 bath, 2 car attached garage.

That could be no garage (when all the other homes on the street have one), backing up to or on a busy main street, bordering or in ear shot of active railroad tracks, in airport flight paths, or where the subject property sits next to or across from a trashed house.
