This makes my offers get presented in the best possible light, and more often than not, gotten accepted.  

Lots of places, especially multifamily units, have electricity the landlord pays for - outdoor lights, hallway lights, swimming pools, laundry, hot water, etc.

I also like the speciality paint store (where I go Ben Moore, for example) just for  consistent service and expertise (hit or miss at the big box there).Then hard to beat the old school prep with tsp and  a good sponge mop (just damp) and rinse with clean water (damps sponge mop)...and primer for major color changes or spots  and stains..The good paint in luster you can clean also makes turnarounds easy...clean the walls (as mentioned) and you may only have to touch up..Finally, if you can go with one color/brand for the interiors of your rentals you will save time trying to match color or organize endless paints in your garage...best of luck

If your metrics support better response to a particular smell, then you'll be able to state within reason that a certain scent actually has effect on persuading an unsuspecting home owner to unload their property for a 30% discount.In my previous life, I dabbled in such new-fangled marketing management concepts; smell, color of letter, time day of week (Thursday, Fridays & Saturdays are the happiest for a person!

Consider a cream color, this give it a warmer feel. 

@Matt GeertsIf your banker is telling you they would consider cash in your account to be "seasoned" after 31 days, s/he is also telling you their diligence is a little light or they are willing to "not notice" certain things in the interests of underwriting a mortgage.If the LoC is longstanding (i.e. the 90-days Luc mentioned above) then it will be factored into your credit worthiness and DTI and still have an impact on your ability to borrow.  

Light switches?

As they break, I would replace with regular light fixtures.

They then did some light rehab and ended up selling on MLS for more than I thought it would go for fully rehabbed.

My 2 cents worth on the Than Merrill and Fortune Builders thing:  I heard the radio ad so I must give credit for him lighting the fire under me to stop thinking about it and start DOING it.
