In general, investment properties require at least 15% of the purchase price as a down payment. Why? First, there are no government loans are available for secondary residences — only privately backed and funded loans. Second, investment homes are traditionally at a much higher risk of default than primary residences. This requires lenders to tighten restrictions on loan eligibility.
There are many factors that can come into play including the number of units, as well as debt ratios and assets.
