Wear and tear.  

noCost for tear out and replacement of br tile and putting carpet down might be about 750-1000 for the 3 bedrooms.  

Even best case scenario your tenant is super clean, there is still wear and tear on everything that you will have to pay to keep up with.

@Shane BrownMost states allow you to keep the receipt-costs for any repair that are necessary (beyond normal wear and tear).

Major renovations are planned: new roof, new HVAC, tearing down walls to increase HLA, licensed contractors on the premises, and some earthwork around the house to prevent rainwater drainage going through the house foundation.Thank you in advance!

@Luz PaganWhen you say you want to enlarge a room, do you mean to have an addition to the house built, or do you mean you tear out a wall and combine two rooms?

Both A and B are multi family apartment buildings.The properties are worth around 1.5-2m.I wish to keep A but sell B; preferably in a tax-deferred manner.A is in an area that has been rezoned and I wish to tear down and rebuild the property as the current building is old and I can get more than 4x the square footage because of the new zoning changes.Is it possible to sell B and use all of the proceeds to fund the development of A in a tax-deferred manner?

Yes, you can charge them, and you can sue them, but you can't recover 100-year old woodwork original to the home if someone decides to tear it down and replace it with new plastic foam board molding.

Its just not right that someone else can just tear down your litter and replace it with their litter. 

The labor intensive part will be roof and tearing up carpet and installing new floors.
