German land sale puzzle and translation please

[fullofsurprises]

I have a document of a property sale between Mr A and my GG Grandfather (Mr B). I was told the sale occurred in 1829.  The problem being that my GG Grandfather was born in 1822 (making him 7 years old in 1829).   
I know this Mr B is my GG Grandfather as the signature on the document matches other signatures I have on other documents.
There is, however, another date within the document (1850).
I know that that Mr A built a house on this piece of land in 1835 so I was wondering if the 1829 date relates to the original purchase of the land by Mr A and the 1850 date relates to the sale of the property to my GG Grandfather. 
I have posted images of the reference that relates to 1829 and that which relates to 1850.
I am hoping that someone may be able to translate both parts which may clear up the puzzle.

If possible could I please have the german transcription with the translation?

Thanks in advance

dem Verkauf des ? Guts zu Sprendlingen bts?  --The sale of the .......(name of the Estate, seems something large) in Sprendlingen

3.  Dem Verkäufer bleibt die Benutzung des ? mit? Haus? bis Ende 1850  zugestanden, wogegen
     er eine Vergütung von einhundert Gulden bezahlt.

3.  The seller has the use of the to the end of 1850 and has to pay 100 Gulden for it.

Hi Peonie,

Once again you are a gem for your help. 

It took me many years to track down this property but the patience, hours of research and many letters to Germany paid off.   Sadly the estate is no longer there.

Thanks for the link.  This was one of my best research sites which lead me to

which were absolutely fabulous with their help.

Thanks once again.
