Wayfair pro line has excellent light fixtures and other items, that would look great in a STR rehab and help keep costs down as well. 

I told them when they moved in the hot tub and AC were luxury items that came with the house, but if they break I would not be repairing or replacing them.

There are a few Categories that I have broken into their own calculations considering there may be cost savings depending on strategy employed.A flipping spreadsheet should have line items for every potential renovation option and the things needed.

They may charge based on volume or weight.Local Waste Management: Check if your local waste management authority offers bulk item pickup or special services for construction debris.Let me know if you have any other questions.

I include a generalized listing of items such as " Property including, but not limited to: clothing, toys, cookware, and other items." 

The problem with capital contributions is that the deduction must be amortized, with varying schedules depending on the classification of the items purchased.

The numbers should work out if I price those items correctly AND not everyone takes advantage of it.

Quote from @Dario De Pasquale: Hi everyone,I am a small STR investor and in the past few years I have been investing in both stocks and real estatewith COC returns of about 20% for the past 3 years.I am considering diversifying my portfolio with LTR and I know that returns there are going to be a lot smaller.So I was curious to know if there was a rough formula that could include mortgage paydown, tax advantages, and estimated appreciationto be able to compare apples with apples.I am only familiar with Cashflow, CoC, Cap Ex, and IRR.Personally I look beyond those items when I invest in real estate.

Separately, I use apartments.com to collect rent, security deposits, bills, etc - also free for you as the landlord and the tenant.Third - to write off items for taxes, I'd check with your CPA but in general, it would be anything you spend money on with that property, including mileage going there.Best of luck!
