currently I am using free skip tracer but It didn't work most of the numbers are all wrong or didn't connect at all. I'm thinking to use something that need to be paid or if there is a great free website let me know ....

Quote from @Itay Heled: I manage nearly 400 rentals and demand is high.

Medford (North Boston) happens to be a low supply/high demand market so I absolutely need to get more comfortable with consistent rent increases but those increases need to be researched and in line with the market. 

Here are some key steps to get started with the BRRRR method:Keep Learning: Stick with reading and watching videos from experts like David Greene and Brandon Turner.Get Your Finances in Order: Save up for a down payment, check your credit score, and look into getting pre-approved for a loan.Research Markets: Find neighborhoods with growth potential and high rental demand.

The Shadow Ln property presented a high-demand location and a competitive purchase price.

But, once you do build some wealth and have a high income, you realize how much you can save/make by owning the right real estate - numbers that far exceed any cash flow you might make on a property. 

Purchase price: $37,000 Sale price: $65,000 Land deal as is / buy low sale high.

@Phillip Austin we've looked into these and it's our opinion they should only be used with Class A tenants, maybe Class B - deifinitely NOT Class C or D tenants.Several companies in this area will no longer allow S8 leases or tenants under 600 credit scores - because of the high number of claims & corresponding claim amounts.

•Tenants demand prompt, high-quality service and without caring about cost •Vendors seek to earn as much compensation for their work as possible.Balancing these needs requires thoughtful stewardship, strong communication, and a commitment to fairness.

If you go in that direction, I highly recommend speaking with multiple franchisees from each brand before making a final decision.
