I just bought a house, and put 10% down on the house. What I learned:

- PMI is really not as expensive as you might think. I pay ~$150/mo extra and all told my mortgage is just over $2k/mo

- PMI rate depends on a LOT of factors, including your lender's terms, your own credit history, and even the amount you put down. Your PMI gets re-evaluated yearly and the closer you are to the 20% equity on the house, the less PMI you pay. You can actually even get PMI waived as early as 18% sometimes, if you remember to ask them.

I've not seen it above $100/month. More commonly ~$60-$90. I suppose it depends on what your definition of "significant" is.

Not compared to everything else. Move was $60 with 10% down on a $350k condo. Total monthly payment was amosr $2100 per month including the HOA
