Since you are on the Austin forum and stated you are from Texas, I would be happy to get on a phone call or have coffee with you to help you focus on the task ahead.However, let me remind you, I am neither a real estate agent, or lender.  

Quote from @Shaun Ortiz: One thing that keeps coming up is how some investors start with BRRRR but eventually shift to other asset classes—self-storage, mobile home parks, even commercial spaces.

I use Foremost for my mobile home investing business with the properties I buy and hold.

First off remember the phrase "Once a mobile home, always a mobile home".

How do I get the phone numbers of the owners of the properties?

Out of state is usually easier as mobile notary will often work.

.- Working a W2 as a firefighter, posting and consuming content- Leaving my W2 to dive deep into real estate investing and working as an agent... and still watching/posting content all while business was ok - Deleting social media apps (one have one on my phone that I use 10 minutes or less a day), diving deep into building my business and skills which have drastically increased due to pure focus and increasing my business significantly- moral of the story... focus on the things you need to do in business (dollar productive activities) and life experiences while reducing consumption will increase your success  

Quote from @Crystal Wiley: Thank you @Rob Drum -  Do you assist with and/or are you familiar with other types of long-term rental real estate investments as well such as mobile homes/storage units/condos?

If so, they are different animals.If you go to help.rentvine.com, you will see the phone number.

I focus on land and mobile homes.
