Will home lenders give loans on small amounts say 20k-30?k. I was told by a realtor it would be hard.?

I am interested in buying some low end properties to rent or flip. I contacted a real estate agent in the area i am looking to buy and he told me that 20k-30k mortgages would be hard to get. The homes i have been looking for are in the 20k-40k range and with 20% down the financed part would be in the 20k-35k range.

Is this true?

He further said i should look for a homepath home if i want to look for low priced homes.

Which i guess are foreclosed on fannie mae homes.

Should i try another realtor or try to secure financing for the low end homes first?. I am prequalified for a 80k FHA Loan for bidding purposes on HUD homes. But i never thought getting a low end loan would be hard. Would it help if i went with a 15 year fixed verses a 30 year fixed?

Any insight would be appreciated !
