Selling 2 properties in Miami to buy a more expensive one -- Good or bad financial move?

[Ray G.]

I own a condo and a single-family home in Miami. In simple terms, does it make financial sense to sell both and buy another single-family home that costs what I get for both properties? I am renting the condo (breaking even, so not making or losing money except for equity).

If properties appreciate/depreciate proportionally, this should make no difference, right? In other words, if property A is worth $100K today and property B is worth $200K today and appreciation is about 10% during the next year, that means property A will be worth $110K and B, $220K. Would a property (say C) that's worth $300K today (A+B) be worth approximately $330K at the end of the same year, meaning I'd make the same equity ($30K) whether I keep properties A and B or I buy property C?

I hope that made sense. Please bear with me here. I just started thinking of this idea and haven't done much research. This is one of my first steps after checking payoffs on both loans and the latest interest rates.

Thank you in advance for any advise you provide.
