Just curious is that annual income 40x the monthly rent gross or net income?

Should my parent company hold all of my real estate LLC's even if they are taxed differently (such as between the buy/hold and flip business) or are parent LLCs designed to only protect the several Buy/Hold LLC's because they are of similar taxation? 

Buying a property with existing tenants can definitely have its perks, especially if you're looking to hit the ground running with rental income.

They'll need information on the deal (revenues, expenses, income, etc..), but they should be able to give you an idea of general terms (interest rate, amortization, fixed period, etc..) with some basic information.

If not, they’re fine keeping it, especially if it’s still generating income.

If the STR income is on your tax return it is qualified just like long term rent using this form:  https://content.enactmi.com/documents/calculators/Form1038.C...

The rental income just sits there in a non-interest bearing account until I invest in something.

However, financial freedom isn't just about replacing your current income.

They can only increase property taxes by a certain percentage each year.  

Are you planning to do a 1031 exchange or a trust deed to avoid/ minimize the property gain tax?
