I find this level of underwriting lacking with many flippers as well, failing to properly consider the holding costs, insurance costs, taxes, etc.

Happy Hunting.

Do you have the knowledge and insight to handle any LT complaints and are you set up properly with your bank and security accounts and can easily collect the rent, etc?

Were they properly screened?

Partly for the strong casflow that we enjoy after 30+ years investing along with other reasons.I would probably not buy additional property all cash, but improvements and betterments will be paid in cash or at least quickly.Leverage is a great tool when used properly. 

You need to market yourself on social media, you need to direct-mail (and have an effective strategy because everyone is direct mailing), driving for dollars, hunting on MLS, cold calling (skiptrace), going to the REI meetups and connecting, meeting with realtors, talking with wholesalers (and letting them know you're not a tire kicker), etc. 

When we acquired this properly in 2015, we used to pay handyman 20-25 per hour.

I plan to refi the property after a 12 month seasoning period and put the money back into the HELOCI, essentially re-loading my gun to go hunting again.

Unless you find a properly zoned property, it is no go.Just start looking in places that STRs are allowed rather than try and swim upstream.

Without proper guidance, it’s easy to make costly mistakes that can derail your progress early on.Having access to solid resources—whether it’s books, courses, mentors, or investing toolkits—can help you navigate the unknowns.
