Buying primary with 10% with LPMI or 20%?

[Sovat C.]

Hi BiggerPockets, I converted my primary home into a rental at the beginning of the year and I'm now looking for my next property(s). This is probably more than you need to know but my fiancé, soon to be wife, also need a place to live. We have been renting (which I'm totally against but it made the most sense at the time since we weren't engaged at the time). Our lease is up soon so it made the most sense to buy now. I think I found our next primary home (closer to work for the both us) and the plan was to put down 20% but now the LO says I have the option to do 10% down and pay LPMI which was only 1/8 point higher than the current 30yr fixed rate. It almost seems like a no brainer to do the 10% down and PMI and use the other 10% to invest! I'll get best of both worlds. The only ways I see it not being a good idea is if I could not get a higher return on my next investment than the PMI amount. Am I over looking anything? Thanks in advance!!
