My wife and I are currently flipping our house and plan to move later this year to make it a rental property. While living in it as a primary residence and doing small and large projects during that time, are we able to use funds from our business account (an REI LLC that will be used to hold the property in the future) or should we only expense from our personal account? We are looking to build transaction history for our business for future lines of credit as we expand our investment portfolio and look to fund that/other projects in the future.
