You can get a bargain depending on repair cost...Determine if major repairs needed(roof, plumbing, electrical, HVAC, foundation).

None of the items you mentioned are emergencies but should be fixed within a day or so.An emergency would be something is on fire, a water leak that can't be contained with a bucket, a gas leak, or an electrical issue causing sparks or smoke that may result in a fire.  

If you chose a good property by carefully looking at plumbing, heating & A/C, electrical, foundation, structure, roof, location and price, then you should be well positioned to be able to successfully manage these duties.

Ticking me off with incessant calls, bugging the neighbors with your noise, just being a PITA?....

LInks and Info below: According to the Massachusetts General Laws Chapter 186 Section 22, A landlord may cause to be installed by a plumber licensed in the commonwealth, at the expense of such landlord, submetering equipment in the landlord’s building to measure the quantity of water provided for the exclusive use of each dwelling unit, provided that such equipment meets the standards of accuracy and testing of the American Water Works Association or a similar accredited association; and provided further, that a sub-meter is installed for each dwelling unit in the building and for the common areas of the building, so that all water used in a building is measured by both a primary meter and a sub-meter.The practice of utility billing for natural gas, trash and electricity is prohibited in the state of Massachusetts.

Other costs must be entered by you in the Rehab estimate section (like water/sewage, Electric, gas, lawn care, HOA fees, etc).  

Instead, use a good specification which tells bidders they need to anticipate things such as the need to raise or lower and electrical box to install a cabinet and a good schedule for the work to obtain firm-fixed price bids.    

We usually give 25% up front purchase material ourselves and upon passing first rough electric inspection he gets 25 %.
