It doesn't help as much as you've implied since 1) you need 20% of the sticker price for the down payment, and 20% of $200k is more than 20% of $130k, and 2) in many jurisdictions you pay tax on the market value, so your taxes go up whenever mortgage rates fall and prices rise.

FHA mortgage down payment is 3-5%. There’s frontloaded mortgage insurance as well as ongoing monthly mortgage insurance, but the credit score and down payment requirements are very low. Most people with a pulse qualify.

If you come with enough money down, you can get a hard money loan with 70% loan to value (30% down) 1 day after bankruptcy or foreclosure.

Is this true any longer? I assumed you can get into most houses with 10% down, so long as your credit and earnings are good.
