Secondly, he went on to mention it cost him $300 to heat 2 rooms for one month over this winter, his concern was the insulation.

Hello, first time poster and would appreciate some feedback on a few areas of concern as I look to expand my buy and hold portfolio. 

My concern is that what if the existing shareholders don't want to sell the shares, then, will they become a partner in the deal or just continue owning the shares equivalent to the apt sq ?

They are trying to tell me they don't carry insurance to save on costs..... concerning to say the least.

One is in a rural area and the local authorities don't care unless there is a complaint filed, so officially illegal, but not a concern.

Also, none of the prices or descriptions (addresses) show up in market place ads.

(about 1/4 the way through both) Im hoping to find some answers in here to my concerns but i haven't quite hit them yet.So I thought I would ask... 

do some or all of the above places i mention give cause for concern?  

When i am uncertain about a new property and the rents it will fetch, i put out a craigslist ad with the address and whatever pictures i can get my hands on and market it for the rents i want. you should know by the response in a couple of days if the rent is too high or low. 

Once you have an address of a property that appears to be in distress, you can go to the county assessor to find the owner (even online in some counties) for free (if you don't value your time), or you can use a paid service that will give you all the details right on your phone while you are standing out front, owner or non-owner occupied, value, comps, equity, vacant, even their phone number.
