They're paying income tax at home as well as a higher property tax here.

I don't see a way to get equity without taxation.

I'll ask @Bill Exeter to weigh in here as the expert, but this is my understanding:To defer ALL taxation with a 1031 exchange, you must purchase a property/properties that equal or exceed the sale price of your relinquished property.

I recommend you consult with a CPA who knows both real estate and pass through taxation to assist you

A Corp. can be very expensive with double taxation if not careful.If you are truly a wholesaler, you have limited liability so a single LLC should do the trick.Talk to a local CPA.

I personally went on MD's Assessment and Taxation and found that no one has redeemed ground rent through their department. 

As of now, corporations pay tax at the entity level and then when the corp distributes its after-tax profits to you, you pay tax again as an individual.

From my understanding an LLC would essentially create a corporate veil and restrict my taxation to up to 35%.

. - financing, regulation, taxation are all different here.

Entity with income of $1 million or less doesn't have to pay any Franchise tax.Hope that helps and you can file more information on Texas Franchise Tax at http://comptroller.texas.gov/taxinfo/franchise/
