Write them down, put them in front of you, and focus all of your energy on them.I have 45 units that I have acquired in the last 3 years, and I plan on buying another 50 in the next 18 months.  

If you're planning on only using rent to cover all repairs and expenses, you can be easily burned by an AC that goes out or a roof that needs to be replaced.

These tanks, and direct vent gas furnaces/boilers, can be plumbed directly through the side of the building (foundation wall, sill plate, etc) provide the exhaust exists the required distance from an operable window, door, or other air intake.From an energy efficiency stand-point, direct vented fixtures are preferable as they are not taking their supply of combustion air from the conditioned space of the building (are you have already heated), causing colder, external air to be drawn into the building.Additionally, as Pat has pointed out, direct vented fixtures reduce the risk of natural gas/propane or CO being drawn back into the conditioned space of the home. 

Buy a home or condominium unit in a VA approved project.Build a Home.Simultaneously purchase and improve a home.Improve a home by installing energy-related features or making energy efficient improvements.Buy a manufactured home and/or lot.My Thoughts: Condominiums – Personally, I will not buy a condominium.

We created that modern, lofty feel in a burned out old multi.  

The owner is old timer kind of guy and I can tell he is starting to get burned out.

Sadly getting burned a little always helps you on the next flip! 

A guest fell in the fire pit and was badly burned incurring $265,000 in damages.

I could go on however I'm typically a bit burned out after a heavy rehab project is completed and sold.
