Property radar is a great tool I can't see how anyone in CA who wants to score deals does not have that app on your phone... its ridiculously affordable..

Whereas BL has multiple ways to track and engage with potential leads, in my opinion, it is not for the novice, whether in using tools or in real estate in general.   

If you have a good agent, trust your agent, they should be a great guide and tool for you.

BP has an agent finder tool you can use: https://www.biggerpockets.com/agent

A HELOC is powerful tool that should be used in specific situations.

would not surprise if younger kid would go back to live w/ their parent, would not surprise also if househacking would be more relevant as that's the only tools for homeowner to go against job losses ..... life may go to normal in 2025.

@Chris Witham Bigger Pockets has lease templates under the tools tab at the top.

Also a seller concession is a good tool to reduce closing costs and carrying more than necessary on the primary. 

@Cole Payton A HELOC can be a great tool but it is totally different than a DSCR:- DSCR is a debt service coverage ratio loan where the bank says we will lend 80% LTV and the rent must be 10%-15% above your monthly payment. 

Get pre-approved for a mortgage, conduct site visits, use analytics tools, network with investment groups, monitor foreclosure listings, and look for areas with long-term growth potential.
