If it is a contractor that is more organized they will likely do this already, if they are shooting from the hip "based on experience" they will likely just give you a total $ value. 

Regards, ClarkI'm curious, @Zhenyang Jin, with a DSCR at 1.30x, what are you total operating expenses relative to your EGI (Rent after vacancy expenes)? 

The letter also states the total non-rent items currently owed by the tenant, such as accumulated late fees or repair charges.Also very important, the tenant states they have no unresolved issues with their current landlord, except as listed in a space provided, and they have no current plans to cancel their lease under the Service Members Civil Relief Act or for any other reason. 

Total rent s/b minimum $2,250 but with housing vouches, $2,550

The recipient inherits your cost basis (what you paid) for calculating capital gains or depreciation.You and your spouse can each gift $17,000/year per recipient under the annual gift tax exclusion ($34,000 total).

I totally agree with @Caleb Brown, especially the part about consistency!

Or would it be the total equity - so the difference between 450k and remaining mortgage of 120k?

Third total! 

Totally up to you.

We bought a new build years ago (and sold it 3 years later when the market turned up) and our TOTAL cap ex was $550 over the 3 years.
