I was reading up about it, and saw that the cons of oil heating include needing to top up the oil supply, lower efficiency (than gas and electric), and potential leaking of tanks leading to environmental issues.Is anyone familiar with oil heated homes?

My basic underwriting making some standard assumptions on HOA expenses, 20% down, 7% interest rate, 30 year mortgage, utilities, supplies, and maintenance costs shows a loss of about $22k per year if you are self managing.

The country simply does not have enough affordable housing units, and the new supply of affordable housing units is not keeping up with new demand.

Because of inefficiencie s and the fact that the boiler rans 365 days to supply domestic hot water the tenant's oil bill the first year was $5,900. 

With this property I racked up some credit card debt, around 20k and I need another 20k to pay contractors/supplies.

While they’re out partying, you’ll be home learning, analyzing deals, and honing your craft.

The limited housing supply has resulted in increased competition among buyers and higher prices. 

Dig and remove around 200 square feet of an old concrete driveway, frame and lay down the concrete (concrete will be ordered from concrete supply business) and complete a brick ribbon around the driveway.

Perhaps there's ample supply in Columbus Ohio but what parts of Miami?

That usually creates a big supply of rentals on the market that it 's hard to be absorbed and create a race to the bottom in prices, as all the properties are pretty similar and in brand new condition.
