Any advice for LSM Land unsoliticted offers for my property?

[Reuben Gathright]

On 2/8/2023 LSM Land sent me a letter stating:

Hi Reuben Gathright,

We are a real estate investment firm based in Austin, Texas. As we were researching the county public records, we found you as the owner of a property that meets our general investment purposes. We are very interested in purchasing this property from you.

Give us a call today xxx-xxx-xxxx and we will make you our highest and best cash offer the offer price will depend on several characteristics such as access to utilities, buildability, paced roads, slopping, back taxes owed, HOA dues etc.

They included a parcel number and the legal description.  Out of my extensive portfolio, the one property they want to buy is in Calcasieu Parish, Louisiana and land locked.

On 2/16/2023, I called the phone number provided a secretary said their agent will call me back from a number with area code xxx.

I have also received to unsolicited phone calls from buyers in Louisiana this month about making an offer on properties in this small region as well.  

Should I call LSM Land back today?
