I’m thinking of selling life insurance part time to save money or should I just put all my focus on real estate?

You need to talk this through because everyone has different life and tax things to consider.  

Do you read every detail of  terms and conditions on a website?

The reason most houses built today have forced hot air is because you can use the same ducts for air conditioning so it normally ends up cheaper.

I'm selling a piece of land and someone asked me what condition is it in...

2) what would it be worth restored to clean and habitable condition?

You are interested in real estate to get some place in your life, not spend it dealing with dishonest idiots.

So yes, always rely on prevailing local market conditions....but expecting some huge correction, they simply do not happen very often.And looking at simply the price of a property is a mistake.

I much prefer a SEC 8 tenant in a sketchy neighborhood or street, because finding someone who both verifiable and reliable income that meets my incomes X rent requirement is tough, and one life bump will cause the rent to go unpaid.  

Another 4 unit a few miles away, in worse condition, sold for $337k, so I know theres some equity in this one already.
