Is it possible to purchase a home from someone, and give them the first right of refusal to buy it back at a specific price at a later date?

The main house is completed and as far as labor, I spent $40,000 on just labor and that includes everything from full gut demo to finishes.We are talking about a 4BD, 3BTH two story 2400 ft.² home with a bonus room.This was a full gut job, replaced…12 Windows (new construction)2 sliding doorsTook out all carpet throughout.Took out this ugly 2” thick tile from half of the downstairs portion.Removed popcorn throughout the entire houseTook one wall downA little framing workReplaced entry door 80” x 92”Drywall patchingSmooth drywall work50 recessed lightingAll electrical neededAll plumbing neededNew cement walkway instead of one walk to the front door I created two steps with two lights in each step.Install kitchen cabinets, excluding countertopInstall all three vanities3 bathtubs with one being a modern standalone tub in the masterAll tile work (bathroom wall & floor, kitchen backsplash)Installing of all hardware, faucets, showerheads, etcInstalled 8 single panel doors with hardwareAdding self-leveler after tearing out that thick tileNew LVP flooring throughout the entire house except bathrooms,all baseboards, trimsPainting the entire house, painting all the doors, painting the outside trim.Reframing the outside balconyReframing the fireplace to install new linear modern electrical fireplaceand they took care of the two trash bins.I mean, completely redone.The only thing that was not included in the $40,000 is landscaping, counter top cut and install and of course the ADU which I’m currently working on now.So my question for my fellow investors and contractors did I pay too much?

When we're 60 days out from the lease termination date, I send the tenant an email / letter asking if they intend to renew.

Hey fellow real estate enthusiasts,I hope everyone is doing well and staying safe during these times.

This notice contains the homeowner's name, auction date and in some cases a description of the property/principal loan balance. 

Should we be doing this HELOC if we are unable to pay it back in full at a later date. 

At one point I even tried working with the tenant to see if a different due date would help based on when he was getting paid, but he said he was fine and his new job would help him get ahead.

Quote from @Donna Brake: Start the eviction process on the earliest date allowed by the law and your lease.

Something else I noticed on the first page of Offering is "The notes are being offered until the earliest of...[] December 31 2024, which may be extended in our sole discretion, or the date on which we terminate the Offering."

The goal of an investor is usually to establish the start date as early as possible, not delay it.
