When a buyer asks for seller to pay closing costs...

[Carlos Rodrigues]

When a buyer asks to pay for all closing costs, exactly what would the seller be paying for? And how and why would a seller even agree to such thing? On a duplex of  approximately $350,000 in NJ how much would the seller be paying for at closing having this requirement? What about the buyer?

Thank you in advance and I'm sorry for such a lame question. I'm new to real estate and gaining knowledge is my ambition. Thank you for understanding and guiding me in advance!!

Seller would pay closing cost to keep the out of pocket expenses manageable for the buyer thus making the deal possible.

Some of the closing costs are state transfer tax, prepaid mtg interest, prepaid taxes and home owners insurance, title insurance, home inspections....

I can't say for sure what closing cost would be on that duplex but I could guess in the range of 15-20k but there are so many variables.

Maximum closing cost assistance is often limited by the type of loan the buyer is using and the LTV
