Sometimes you claimed a lot of repairs on your 2014 return but not your 2015 return so showing a 2015 return will allow your loan approval to be shown in the best light to an underwriter.Since its now 10.25.16 and we're 10 days past the corporate return filing period of extensions I would assume you have your 2015 returns.If the income is good you can use that income, if not there are ways to document the use of the other income method of 75% of gross - PITIA if you did substantial repairs to your properties upon purchase or if the tax returns were not an accurate depiction of actual income, whichever method is best from a qualification stand point.

Personally, I would go with the laminate if it is a light color.

Can anyone shed some light for me on how to use notes in real estate investing?

Before jumping in you really need to decide your area of investing. how much do you want to put in ... time, energy, mental fortitude (the 3 "t's"  tenants, toilets and turnover). a REIA club will help you with that. freebie seminars will help you as well.... if you learn one thing that will help you avoid mistakes, money left of table, it's worth it.

You would need to do an energy audit and the auditor will give you recommendations (cost breakdown) on improving the energy efficiency of the home.

so you know exactly what to work on and where to put your energy.

Chalk it up to experience, too messy to spend time, money and energy on it. 

Little extras when I am servicing a unit anyway (like a new toilet seat or faucet or porch light unexpected), greeting cards at holidays, common areas decorated for the season or trimming a tree, weeding, etc. without being asked.  

You want to be in light so you can put a tenant/buyer in ASAP.  

I would be adding drywall over the existing plaster walls, can lights, a kitchenette and 2 small bathrooms.
