Though a nice house, the land size is too small for it to even calssify as a mansion...You say the total land comprises of 5 annas (342 sq ft x 5 = 1,710 sq ft = a 3-4 BR NYC apartment) which is too small to even have a small lawn as the house itself occupies 3.5+ annas.  Also, post the interior pics if you want quality buyers who may be interested. 

Although not a mansion, you're right in calling it a "Manson"...BTW, Which Manson?  Charles Manson and the Manson Family or the uber wierd Marilyn Mason?  LOL
