I decided to make a few minor safety repairs off the bat (including carbon monoxide detectors and smoke alarms- I'm not kidding when I say he was a slum lord!).

You can also use carbon fiber straps instead, if you don't want to sacrifice interior space in a finished basement. 

I have heard that too much carbon monoxide will get out.I had a furnace break this winter.

Be vary careful on proper flue and vent design for the furnace, you don't want to either burn the place down or kill someone with carbon monoxide. 4, Call up the HVAC company and have them charge your system by the hour plus refrigerant costs.

Depending on if the hot water heater is gas or electric you may have to 1) run new gas lines and exhaust pipe to correctly vent the carbon monoxide. 2) run new electric to each hot water heater. because the additional electrical demand this would cause you may have to upgrade your service (circuit breaker panel). 

Carbon Monoxide Detectors – Follow on to the discussion, “Do You Provide Carbon Monoxide Detectors?”

@john carbone has a separate thread related to it. https://www.biggerpockets.com/...

Try Wisconsin Legal Blank they have pre-drafted leases created by a Wisconsin attorney and they're carbon copied

Carbon fiber body panels, superchargers, headers and exhaust components, aftermarket wheels, performance pistons and rods, machine work, etc – these parts are not cheap, and the extensive modifications left my car absolutely useless during installations for long periods of time.In total, after spending $17,000 to buy the car that I eventually owned free and clear (excluding interest) and spending an additional $20,000 in performance and other upgrades to end up with a reliable 600hp beast on the streets, I was essentially going to realize a loss of $22,000 if I was able to sell the car for $15,000 - the current blue book value the day I stood in the garage pondering if I was ready to take the leap and sign it over to a buyer.

Note: the basement floor is poured concrete, and is uneven in places, where it seems like the soil underneath has washed away and caused the floor to settle in some areas (not a huge concern at this point).I've had a number of contractors and waterproofing companies evaluate the situation and suggest anything from interior water proofing and wall repair (I-beams or carbon fiber straps), to exterior waterproofing and rebuilding the foundation wall.From my research, it doesn't seem that interior waterproofing will solve the problem, and the I-beams are only a temporary fix vs. rebuilding the wall and exterior waterproof.
