if you think your buyer is getting flaky... can you take back up offers on a deal you are going to assign at closing?

(normally recommended, especially if you are a landlord)- Water Backup: For water damage due to the backup of Sewers or Drains.- Personal Articles: Coverage for belongings that have a special or collectors valuesuch as Jewelery, Furs, Fine Arts, Collectibles, etc...Your age should not be a factor on the pricing but, depending on the company these other factors may get you credits:- Insurance Score (company pulls certain info out of your credit report)It is not your credit score but generally better credit will result in a better score- Time at your job- Education level- time at current residence Good Luck

Once you have multiple properties, you can relax these guidelines a little based on the likelihood of major repairs occurring on more than one property at the same time.....but having said that, trust me when it rains it pours and you should at least have a back up line of credit to cover you in the worst case scenario. 

An oil burner with 2 diverters so each unit can control their own heat.

For example, @Will Wiggins advice is what people typically do and It's a good back up plan, but there is a more savvy way that will pay off huge on your 3rd purchase.   

With that said, my credit is now back up to almost 800, debt-free, and have $30k to use to buy an investment property.

Since about 2012 when it started picking back up, it has been virtually non-stop.

I'm just wondering if it would actually take more energy to bring the place back up to temp than it would to just let it maintain one constant temperature.

Most are clawing back up to zero or with a paid off house, so a couple hundred grand maybe.I paid off 19 units last year, but could never have done anything close to that saving up and paying cash for everything.

For the emergency have a back up plan make sure they are aware of water shutoffs or you have a back up heat plan.
