Repairs made while the property is your primary residence are not deductible, but improvements can increase your cost basis, reducing future capital gains tax when you sell.

Quote from @Michael Overall: Good day, If an investor has 10 rentals and wanted to over time sell them and put the money tax free from a 1031 toward a large purchase is there a process to do that? 

You'll want to put together a personal financial statement (basically lists of all your assets and liabilities) and have your tax returns ready.

Many of the investors I know have dialed back on their private equity investment or have changed to doing debt instead of equity so it was not prime time.

Lower property taxes, affordable housing compared to LA (CA buyers are usually cash buyers because what they net from their smaller home in CA can get them a bigger home here, often covered by what they net from their CA sale), allergies (smog), and politics. 

However, before you do so you should ensure that your revenue from rental income covers ALL your property expenses in the townhome, including mortgage, taxes, insurance, maintenance/repairs, vacancy, property management, etc...

High taxes.

To succeed, focus on properties in high-demand neighborhoods like Pecan Grove or Aliana, and ensure your cash flow analysis accounts for high property taxes, potential HOA restrictions, and flood insurance costs.

I have a confession: my only duplex, which I gave owned now for 2 years and recently moved out of from a house hack, has proven to cost me more to maintain/pay taxes/repair/fix etc to the point where my cash flow is close to zero.
