Need Advise on quick turn around

[Stephen Mcnulty Jr]

First ever question so thank you in advance.
CT resident looking to purchase an investment property around February 2023 . I want to use a 203k loan . Looking for property’s well under market value. 3-2-1 families all fall into this category for me. What should I look out for with this type loan and how fast can I purchase another property once I commit to this type loan. Are there other loans more suited for this type turn around with out a 20% DP

Thanks again
