The unit currently has window units and forced air heat. 

My list includes an electrician, heating & air service, plumbing outfit (though I do most of this myself, I was a plumber in an old life), roofing contractor, and a couple of general handymen.

Your utilities number looks low - $200/month for cable, wifi, heat, electric, water???

Heat of the moment retaliation from the unwarranted scolding you received.

Get a letter from the zoning board/dept. stating that the property is a legal 3 family.Is the heat separated?

Does he pay for Heat?

@John Jacksonand I are good friends.He lives in Texas and has mastered lease option assignments in TX, not easy in TX.In 2002 he and I became friends, and I trained him on the basics of cooperative assignments, where you enter into a lease and an option with the seller as a principal, not as an agent but a principal.You then assign the deal for a fee of generally 3 to 5%.In the example above for $100Kthey owe $95,000If they listed for a $100K, sellers would have to pay the cost to sell, which include the following:– commissions 3 to 6%– closing costs 2%– sellers concessions 3 to 6%– vacancy costs we have to pay the PITI while is being sold, let’s say $1000×4 months, and this includes electric , heat, watering lawns, garbge, and so forth– spruce up costs, such as painting a wall or replacing a carpet, or fixing a fence.Many sellers don’t have a lot of cash in the bank, and they don’t want to get more debt on a credit card fix up their house and they can sell it.So this particular seller would probably pay 10% to 15% of the value of the property to sell with an agent quickly.

Does anybody have any experience in tankless water heating systems?

When everyone stopped bidding and we were left in a bidding war between us and another investor, it would have been easy to get caught up in the excitement of the bidding and the heat of the moment, but before I bid I would look at my excel sheet and knew my numbers.

These buildings are block structure, each with their own bathroom, no furnished heat or AC but some tenants have added it themselves.
