In the podcast Jered Sturm, Brandon Turner, and Dave Meyer talk about different value add strategies like doing a rub (sub metering water), increasing energy efficiency with light bulbs, and renting out washers and dryers to the tenants.While I was going to Southern Utah University to get my Bachelor's in Engineering and Technology I stayed in several different apartments and got to see both the good and the bad of many apartments.

I can see ECA DuctWorks investing time and materials in exchange for light returns after sales.

@Abigail Timbol You wouldn’t get very far on a journey if you sat in the driveway waiting for all the lights in town to turn green.

While much of the structure is still there the support beams that hold the weight of the house is damaged. 

If it doesn't, load up the belt sander with 100-grit,  sand the problem area again enough to take off the poly, stain the wood lightly with an oak stain (usually the best stuff for faux-aging oak will be marked "golden oak"), and poly it up again.

You can add lighting to them too.  

However, the time commitment is not something to take lightly. 

Instead of having a vacancy and being out 100% income until you fill it, your other properties would be carrying the weight of the vacancy all while your tenants pay down your loans for you.

How much weight do you give the information regarding the neighborhood?

We have old wood double hung windows with iron weights (1914 house) with 1950's storms and we are just starting to shop around.
