So, I'm going to re-face the drawers and doors on it and replace the counter-top on it with granite and install a vessel sink.  

It's a lot like toothing-in tongue and groove flooring... typically on the last piece or two have to have the tongue or backside of the groove removed to install and a dab of adhesive often does the trick.If you opt to paint, use a primer/sealer first (such as Zinnser or Kilz), but know that the painting will be noticeable.

To avoid sewer hookup issues, wastewater will be dealt with by using a local Honey Bucket service that will install a holding tank and keep it emptied. 

More than 20 exposed nail heads on shingles allowing water to leak in.Incorrectly installed lashing and porch materials.

On both units, I've installed sediment filters, industrial strength water softeners (not the cheapo ones from Home Depot), and reverse osmosis systems.

Usually big-tickets items (roof, furnace, etc.) have really good rates within financing thru company that installed them.I also add extra personal touch items yearly, just before giving any rent increases

I like to have a set of pics from before moving and to compare ... they may remove towel bars, etc and you may forget that there used to be a towel bar there ... until the next tenant asks you why there is no towel bar and requests that you install one.    

I did this myself, and yes it met all the requirements recommended above.You will need to host any open houses.

You could add LED lighting installed hidden away under the cabinets, this provides a great look, extra light for working in the kitchen and adds value at a low cost.If you're looking for new flooring, possibly look into buying bamboo floors as they're popular currently and thus are often over stocked and can be bought from a company like lumber liquidator for around 1/ per sqft.This sink fixture is often the only thing needed for the sink to look new, getting one with a hands free feature would be an added cost item.Another low cost-high reward option would be replacing the counter top and repaint the counters and cabinets. 

I like using natural stone in my flips, and that doubles the installation price almost instantly.
