ulti-unit rental properties, also known as triplex, four-plex and five-plex’s, are the more sought after properties by the average real estate investor and want-to-be real estate investors. When purchasing rental properties the more you put down the easier it is to make a profit and to qualify for the mortgage. However, at the same time the more you put down the less properties you will be able to purchase — it’s a catch-22. Down payment requirements Depending on the lender used, the down payment required to purchase a multi-unit rental property is between 20-25%. I give a range on this because it will depend on how many units are in the property being purchased. Although it is possible to purchase a multi-unit rental property with less than 20% down (as little as 12%) — this is on a case-by-case basis. Finally, if you are looking at purchasing a multi-unit rental property and will be occupying one of the units yourself, then it is possible to get that property for 10% with most lenders and as little as 5% down with others.
