There are some programs out there to assit. Most lenders want to see the buyers put some money down. There programs out there such as CDA you can get help. FHA + and more. if you need help finding your home let me know.
That will depend on your income and the area you choose. There are special programs for police officers and teachers, incentives for closing help assistance for military members, county programs that assist with up front expenses based on income or in certain targeted zip codes, and state funded closing help and down payment programs if you qualify. I have a great local lender that can give you guidance. Message me for info.
Best of luck!
