Hi,
You have not mentioned the type of property sold.
If the property sold is not a residential house property, then you cannot claim benefit u/s 54F as you own more than one house other than the new house (I assume the properties you mentioned are House properties).
If the property sold is a residential house property, then you can claim full exemption from the Long Term Capital Gain u/s 54. In Section 54, there is no such condition regarding no. of houses owned other than the new house.
