I just look at areas with large medical companies as employers.

Needless to say, one medical catastrophe could wipe out all my hard-earned investments. 

@Brie Schmidt I found the following under the Massachusetts general laws defining condos:''Common areas and facilities'' shall, except as otherwise provided or stipulated in the master deed, mean and include:—(1) The foundations, columns, girders, beams, supports, party walls, common walls, main walls, roofs, halls, corridors, lobbies, public stairs and stairways, fire escapes and entrances and exits of the building;(2) Installations of central services such as power, light, gas, hot and cold water, heating, refrigeration, air conditioning and incinerating;(3) The elevators, tanks, pumps, motors, fans, compressors, ducts, and in general all apparatus and installations existing for common use;

You can be on the middle, be understanding with people in case by case scenario, if you have a long term tenant that is good and may have a sudden medical problem you can workout something with them about rent being late, but remember that if you don't charge for rent you are giving money away so see how important that is to you, can you afford to donate money to them?

My understanding is that these loans are short term in nature, are you planning to sell these properties before maturity or you planning to roll them over into a long term debt facility?

However, my husband and I did buy his parents home on contract after they moved to an Assisted Living facility.

(selling medical devices) so I'm trying to get into real estate ...

This includes the provision of goods, services or facilities to the plan.

Over 6,000 units and 30+ Self Storage Facilities under my belt - what would I do first if I had to start all over from the beginning?   

below ground means it's a burried tank, most likely the building dept will want it excavated and new one installed either in the basement or above ground. if you buy a property with a below ground oil tank it can be an environmental night mare if it fails a pressure test and is leaking. the soil around the tank will need to be professionally removed and hold off to an approved facility. you will have the Dec and building dept watching every move. make sure you get quotes to get an approximate idea of costs on this and add that into you purchase offer, be very well prepared to take on a project like this when buying with a below grade oil tank
