What are the differences between an investment mortgage and a personal mortgage?
I used to own a few investment properties, so I'm pretty familiar with this.  As MrChrister mentions, lenders see investment mortgages as higher risk. People who fall into financial trouble are much more likely to let their investment properties go than their personal residence.  Consequently, the interest rates and downpayment requirements are generally higher. Typically a mortgage for an investment property will require 20% down, vs. as low as 3-5% down for a personal residence.  With excellent credit and some shopping around, you could probably do 10% down.  Interest rates are typically about a half-percent higher as well. You'll also find that the more investment properties you have, the harder it becomes to finance new ones.  Banks look at debt-to-income ratios to determine if you are over extended.  Typically banks like to see that your housing payments are less than 20% or so of your income.  However, with rental properties, housing payments generally account for far more than 20% of your rental income.  Other income you have can offset that, but after buying 2-3 houses or so, your DTI generally creeps into the range where lenders are uncomfortable lending to you anymore.  This is why you'll find that many rental properties are bought on land contracts with owner financing rather than with mortgages.
