My name and my daughter’s name(s) are also in title and the loan.I have really good equity in both properties (six figure) with great interest rates.At some point my daughters and their husbands will move out to upgrade to something bigger.I want to turn these properties into investment properties after my daughters move out:  thinking the best way is to convert in my name only.Also considering leveraging the equity in the properties to help buy new homes/townhomes for my daughters when they are ready as well.Wondering what the best strategies would be for me to expand property portfolio, minimize tax impact , create more passive income while continuing to help my family grow.I appreciate any advice! 

Yes, property taxes are higher for investors but not terrible. 

By paying a commission and taxes, you get more money from the property by doing a Refi. 

I have created a lot of loss in my taxes over the last few years and now want to get a mortgage for a new primary home.

Once you close on your property:- You need to get a Phila tax IDhttps://www.phila.gov/services/payments-assistance-taxes/tax...- Then you need to register for a commercial activity licensehttps://www.phila.gov/services/permits-violations-licenses/g...- Once you have a commerical activity license you can finally get your rental licensehttps://www.phila.gov/services/permits-violations-licenses/g...All of the above will be done using the eClipse online portal systemIf your property is built before 1978:The system will kick back your application and you will not be able to get a rental license until you get a Lead Safe test.This is when you will hire a licensed 3rd party to come out and doing a lead test for you.

Also, consider the appreciation and tax benefits.

Those are pretty decent numbers.Remember property taxes get re-evaluated every year and can go up every year AND they are kinda high relative to other states.Neighborhoods matter.

What structure would be recommended for holding personal assets and investment properties, including rentals, to optimize anonymity, asset protection, and tax benefits?

As for income verification, I require the applicants two most recent paystubs and if self employed I need their most recent tax return.

You can use defined percentages, like taxes, because they are a product of a specific percentage applied to property value.
