Given the financial crisis, and Thailand's domestic issues - prices essentially have been rolled back to where it was ~2 yrs ago. Very general statement...definitely true in Bangkok. In addition, the Baht has held up steadily, but definitely trending weaker in the last 12 months or so.
Don't expect massive discounts - esp. in Phuket - the absence of mortgages mean people have paid cash and are not holding mortgages. On the other hand, if you look hard, I am sure there are resellers willing to deal. Developer's are trying to hold onto price, but throwing in additional incentives. Resales are marked in some cases 20+% below developer's inventory. (at least in Phuket)
Foreigner's can own upto 49% of the units (not sure if it is based on units/or sq footage) in a Condo, on a Freehold basis, in your own name, but you need to check for availability first. You'll often find buildings where the foreigner quota is sold out... so make sure whatever you buy can be titled in your own name.
Doesn't mean you cannot buy once the quota is sold out, but beyond that quota - to own it on a Freehold basis you'll need to set up a Thai entity etc. Why bother, when you can just buy the foreigner quota.
Any property lawyer can help check and verify that the unit you are considering is title"able" in your own name, on a Freehold basis.
As for visa, if you are considering living here - I haven't used them, but have a look.
Welcome to Thailongstay.co.th If you intend to just visit in/out - while being based in Egypt, you probably don't need the above.
You are 100% correct in focusing on something finished, rather than off plan. Even finished properties, I would also stick to a quality developer, do some due diligence on common charges etc (if it is a condo should be governed by Strata laws etc). Some unfortunate instances of undue markups on utilities, by small developers etc. No different from property anywhere else.
Hope this helps, good luck
