Recently there was a major plumbing problem at 1 of the single family homes and the tenants were not able to use the bathroom.

Mostly mobile homes beside 2 are lots only.  

Would love to help you find your first deal in your home city, let me know if you need anything!

I am intend to retire in 3 years and would like to begin purchasing single family homes in the Dallas area for rentals.

Home Improvements of 50K and is Rented.

Each option has its pros and cons, and I'm hoping to get some insights from this community to make a more informed decision.Option 1: Building an ADUPros:Increased Property Value: An ADU can significantly increase the value of my primary residence.Control and Proximity: I can closely manage and maintain the property since it's on my land.Potential for Higher Rent: ADUs in bay area can fetch a good rental price.Flexible Use: ADUs can serve multiple purposes – home office, guest house, or rental unit.No Additional Land Purchase: Utilizing existing property means no extra cost for land acquisition.Foundation improvements: I will get an upgrade for my foundation which increase house stability.

If you read close the rules are different if owner occupied or second homes vs Investment.  

We purchased the home on 6/15/2022 for $330,000, invested $20,000 in renovations, and sold it for $399,000 on 10/13/2022.

They won't be able to sell their home for the same amount as their neighbor with the exact same house if their neighbor paid 2.5% and they are paying 0%

I ran the spreadsheet that @Scott Trench has on the article "Millions of Americans Should Keep Their Homes as Rentals, Not Sell.
