Here is my take.If you are good with being persistent, this will be key in your future success with land or any other real estate venture for that matter.

They will draw down substantially in a rising rate environment, especially if persistent inflation detracts from landlords' ability to consistently increase rents & other income. 

My broker also received a few subject to offers and when looked them up in public records on other properties he say Notice of Defaults.

I also noticed you have two emails on file with us, and you sent this from your alternative email, which may have caused some confusion.2.

As I'm moving through the house cleaning everything, I'm better able to notice what needs to be removed/replaced, and every other little defect.

Quote from @Deborah Wodell: I've noticed an increasing trend among investors looking for 100% financing or securing 90% financing and then seeking gap funding for down payments and closing costs.

If they are high maintenance, you can also have a talk with them along the lines of if they aren't happy there, they are welcome to give 30 days' notice and not pay the penalty for breaking the lease. 

Right now, I’m particularly interested in the rental market for potential investment opportunities, as I’ve noticed some promising trends in the South Eastern Region.Looking forward to connecting with everyone and exploring opportunities to collaborate!

So would you still serve the owner a “3 day notice to quit” even though they don't live there?

Renting for all my independent life now, I've noticed rentals I've found were on certain platforms being advertised, like craigslist, apartments.com, Facebook marketplace, and landlords posting to their personal social media accounts.However, I can't imagine these avenues being the only advertising methods, when you have something like vacancy to fill.
