Seeking flips advises

[May Wen-Li]

Hi investors!

We have been flipping houses for about 2 years and did about 9 houses so far. 1 of them didnt sell for 2.5months so we cashed out and renting it out instead.  We are currently selling one but no offer after 2 months on the market.

I was wondering usually how long do you list the property before cashing out and convert it to rental? 

What is a reasonable profit in this market? How do you find cheap foreclosures? 

Any good strategies to save in taxes?  

I feel like flip is a good way to get cash flow but rentals are more profitable in long term. Do most of you do flips or both?

Any advise is appreciated! Thanks!
