We should all be watching this data like a hawk.So things have been heating up.

He can do this by doin a manual J or heat load calculation.

You most likely will have title costs, possibly attorney costs if in an attorney state, tax adjustments (costs or credits) water/heating fuel adjustments, some states have transfer fees, any lending costs if you have a loan, and I'm sure there are costs I'm missing.

Not sure how old the home is but you definitely want to check out the roof, electrical, water heater, heating and air conditioning and plumbing at the very least.

landlord's neglect and how they were paying more in electricity (electric heat) almost than rent ($1,500/month), saying how they were given no fridge, heater, A/C, etc. and had to get everything themselves. 

They break without notice, and you are required to provide heat to your tenants.

BUT it had boiler heat so no coated vents or evaporator furnace coil coated with nicotine.On another we had to literally take it back to the studs & remove the old drywall.

It got really tense and heated, he wasn't going to budge, this had to be part of his signature, not negotiable. 

Many areas of the city vary block to block and you may end up missing out on great investment opportunities if you avoid areas solely based on the heat map data.

Does not have any performance clauses (work requirements) but you can edit them in.I strongly suggest you find a way to fix this house, at least, heat, ac, plumbing, sewer/septic and electrical.
