Problem here is, apart from the zoning restrictions of STR, purchasing a property is extremely expensive.

But, i heard there are many restrictive zones in these areas. 

Hey @Martina Su, do a search as there are several threads with tons of info.The bottom line is that there are restrictions all over the place so you should get a good realtor locally who knows the areas and market to guide you.

Some folks haven't been able to list their homes due to the restrictions of the municipality.

Are there any restrictions on re-selling it also as a subject to to a new purchaser? 

Who enforces these restrictions anyway?

Texas does have some general HELOC and second loan cash out restrictions with many lenders..Check in with @Joseph Chiofalo for specific guidelines. 

I have heard that the VA Loans are the most restrictive, as far as a Property can have virtually " NOTHING "  wrong with it, I'E. has to be in Liveable/move in condition as the property currently sits,  in order for it to qualify.Given this, What things will usually disqualify a property for getting approved for a VA loan ?

Meanwhile, a legacy of restrictive local regulations around building has kept supply low.
