Advice - Fix and Flip or Fix and STR

[Desiree Suchodolski]

My husband and I have decided to do a live-in flip with our primary residence that we bought in 2018. We are going to take out a HELOC to do repairs, and after it is fixed up, we expect to be able to sell it for $400,000 more than we bought it and avoid capital gains.

I have also been wanting to get into STR. Airdna would estimate about $140,000 yearly income if we were to STR our property after improvements. If we could get that amount after expenses, we would see a gross of $100,000 annually. 

I am trying to decide on the best investment strategy, taking the $400,000 we would make from a fix and flip and using that money to invest in something else or STR our property and possibly gross up to $100,000 annually. Any help or suggestions would be greatly appreciated.
