Investors & landlords

Thanks for your help!  I just want to confirm I'm doing the correct basis for depreciation.

Parents bought house in 1978 for $71,387

Improvements w/receipts (probably more but don't have documentation: $18,622

 

At time of Daddy's death the FMV was estimated at $365,500.  So his share is $182,750

The tax assessment for 2021 says $259,900

Value of land: $85,827

So I'm not sure whether to go with the tax assessment value as the FMV or what's on Zillow.

 

Please correct me if I'm wrong: 

Adjusted basis would be 71,387 + 18,622 + 182,750  = $272,759 .  This is figure to use for depreciation?

 

Also I wanted to confirm that I can just expense some items that cost less than $2500 using the safe harbor  (I think) method.  Example: $450 microwave, ceiling fans $1500, toilets $250/each. Can I just list them as repairs so I don't have to depreciate?

 

Thanks again for your expertise!
