The Riddle House

Forgive me if this has been covered, I haven't posted in quite a long 
while.  

So, I'm doing my reread prior to DH's release and I'm currently on 
GOF.  Something minor struck me as I read through the first chapter. On 
the bottom of pg4 (American hrdcvr) it says:

"The wealthy man who owned the Riddle House these days neither lived 
there nor put it to any use..."

I'm wondering who this "wealthy man" is.  Who would have a reason to 
keep the house all these years?  Perhaps Dumbledore?  Maybe Lucius 
Malfoy?  Will the house come into play?  Is there a horcrux hidden 
there?  

Just something that popped into my head while reading.  If this has 
been covered, would someone point me in the right direction?
