I will respond as if I actually know, but I really dont and regurgitating at best... Any and all comments showing me where I am inaccurate are HIGHLY welcomed.</p>

As it was explained to me and my understanding of all this...</p>
</p>
If you put a down payment of less than 20% of the value or sale price, to protect the lender if you dont pay your bills, mortgage insurance will be required. There are two types of this, P(rivate)MI and Govt (FHA). PMI is calculated by how much you put down. FHA it is 3.5% I believe. PMI is usually more than the FHA rate. FHA is usually easier to qualify for and I believe you can even finance the 3.5% down as well (dont hold me to that). FHA was to allow for easier home loans for less than perfect credit and without the huge cost for a downpayment.</p>
</p>
Once the principal hits 20% paid, lenders must cancel the insurance, PMI or FHA. This means that if you have PMI but the following month walk into a huge sum of money and pay off the principal to 80%, PMI is stopped. With FHA, it is a minimum of 5 years, no matter how much you pay to the principal. Some FHA require it for the life of the loan (which is a bad way to go in my opinion). </p>

For me with the amount I wanted to put down, the PMI would have been very costly. While I could have put 20% down to avoid any MI, I did not want to cripple my liquid money, as the majority of other money was tied up. I had been shopping for awhile and the place I got was the one I wanted and I didnt have time to shuffle moneys, didnt want to pay penalties, and didnt want to expose myself with money woe should I have lost my job or the like. So rather than put 20% down and avoid any insurance, I went with FHA with 3.5% down, smaller monthly insurance and a 5 year mandatory insurance payment. It allowed me to keep the other money I would have used as a down payment invested in short term and available for the "oh shit" moments, should they have come.</p>
</p>
I also wanted flexibility, should I need to move the place and if I had 20% tied in down payment and took a bath on the property, I was out serious money AND didnt have the protection I wanted (but that was more me being a scared punk too). If you know for a fact that you will keep your place for the long haul and feel ok with the 20% down, any insurance concerns are gone. I wasnt comfortable doing that, but more for personal reasons than really financial ones.</p>
