Judges will sign off on it, but any judgment obtained by a method of service that is not allowed is void.

Obviously the numbers and location would determine which is the best option for me but these would be my preferred methods. 

My experience with friends/some clients is get their numbers via whatever method you can and reach out via the phone.

You definitely want to use a thorough screening method like rentprep.com that gets their income, credit, background check, and call at least 3 references (make sure to verify them by address/job and then their name).  

Used houses in the area sell anywhere from $75-125 a square foot.These are long term rentals that I do not plan to sell.I am reading the Rental Property Investing book and implementing the method that focuses on cash flow and that strategy states you need to have $300 cash flow per month, per property.

This is why this method is so powerful.  

But why would that make them want to use this financing method?

House hacking is the best tried-and-true method for new investors in my opinion.

Have you done any research on what method of investing you would like to do?

I hope to find a single-family home with at least 4 bedrooms, use the BRRR method to turn it into a short-term rental property.
