As some of the other Realtors have mentioned, your down payment will be determined by your individual situation. I have some of the best lenders that could give you a quick answer to what your payments would be and what you qualify for. My advice would be to get a conventional loan to purchase a condo, because VA and FHA loans require the complex to be approved, which will limit your options.
VA loans 0%, FHA 3.5%, Conventional 5- 20% down are typical ,then you also have to factor in the closing costs which are usually around 2% of the purchase price.
Please feel free to contact me anytime to get pre-approved for a loan and/or to start searching for that perfect home. Have a great weekend!
