So let's assume the tenant gets to deduct a certain amount for property tax and interest (for this argument) paid to the government (tax) and bank (interest) through the landlord. Tenant and landlord don't BOTH get to deduct for the amount that the tenant gets to deduct, so that means the landlord is forced to accept a smaller deduction. The landlord's logical response is to raise the rent because he or she was previously counting on that deduction as a component of overall returns on investment. Landlords don't purchase buildings to provide benefits to tenants, afterall. So the tenant just gets a rent increase indirectly due to the tax code. The rent increase is likely to be larger than the benefit of tax deduction, just due to general escalations and aggravation to the landlord.
Land Development often has the same unintended consequences. We often developed a raw piece of land by installing water pipes that would be turned over to the utility authority at no cost to them. After all, the developer is willing to pay for the improvements, but doesn't want to manage the utility after it is installed, and the utility companies have a lot of leverage to simply demand that the pipes and equipment just be handed over for a nominal amount (say $10) just to indicate a transaction. But the federal government says that the $250,000 capital improvement is income to the utility company (a quasi-private entity with governmental authority) so the feds say they want the utility company to pay a 20% tax on the income (just throwing numbers out). So the utility company, in turn, makes the developer cover the expense (now we're up to $300,000 for a $250,000 construction cost). It doesn't end there because the tax that was tacked on is also income, stimulating more tax that the utility company must pay to the feds.
It becomes a law of diminishing returns, whereby the developer actually has to pay 151% (that was a real percentage that was determined in agreement between the feds and utility authority) overall for an improvement that went in the ground and handed over to the utility company. Before you cheer hurray that the developer has to pay, just understand that the developer doesn't really pay that cost. Anybody who buys a home will pay that cost (multiplied even more so for profit margin) in the purchase price. Once again, the government shoots the middle class in the foot when they <say> they are on our side.
