For example, Zillow does a horrible evaluation of my home because it doesn't factor in the fact that I spent over $200K in an addition, full remodel, and a garage conversion into an ADU. 

In addition, the city of San Diego has very unfriendly to LL tenant laws.  

In addition to the above, we also look for property in good schools' areas, low crime areas and in neighborhoods where most of the properties are owner occupied. 

Don't you think your time could be more wisely used looking for additional investments rather than working on the day-to-day stuff?

If this property were to make $225k without the additions based on its size and location, would it be worth it given the capital cost?

Additionally, our strategic marketing efforts highlighted the property's new features, attracting buyers quickly.

So probably at a much lower tax rate than the practice.Any extra income goes to purchase more real estate with higher depreciable basis to offset the additional revenue from the rental to the practice. 

Earn money, build your credit, save up, and invest wisely.

Additionally this hard money lender is at 75% loan to value are there any lenders offering 80%?

So you may end up having to come up with quite a bit of money or additional debt.
