How to create a block with views filter form available on each page of the site? This is for a site of a small real estate agency.

I have a property_offer content type set up and offer type vocabulary, with 4 terms (Buying, Selling, Put out to lease and Take on lease). Then I have created a view with page display, for the front page of the site it lists all the offers, and there is also a page for each of the 4 terms.

How do I create an exposed filter for this view which must be available as a block so I can put it in a region of the site and it'll be available on all the other pages too?
Views support "Exposed form in block", see in views editing page. Set it to "Yes", and it will appear in blocks.
