Go to the different institutions providing housing loans and ask them to calculate and give you the “net” amount of money you will have to pay over 10-Yrs and the “net” amount of money you will have to pay over 20-Yrs. When we say “net” we mean that the money includes everything, the administration, processing and all other possible fees. Note all the different rates that all the different organizations give. This will give you the best idea about the different rates.
Usually loans are disbursed within 10 - 15 days after completion of verification by the institution, documentation (original agreement for sale / lodging receipt) and completion of all relevant procedures.
