Some of the upgrades you mentioned (specifically the smart tech stuff) only help for new home buyers (window shoppers).

@Oli CimetHouse hacking can be a smart strategy for real estate investing, especially in high-cost areas like the Bay Area.

It's also smart to get advice from an expert to check if your property is a good fit for central HVAC.

I always think it's a good idea to try to keep tenants who pay on time and take care of the home so a smaller increase is a smart idea in my opinion.

Hey V.G - You are very smart to be focusing on the Carolinas due to the serious wealth migration that is upon us.

That rent would have easily covered the cost of hiring professionals, the job would be done better, and you would have saved yourself three years of blood, sweat, and tears to focus on your next investment.There is a time for learning and DIY, but you have to be smart about it.

Glass block is a great idea.....I've used that and it is a good solution.I also second the idea to look inside the wall, if you have mold inside there, that could be huge trouble.And if you keep the window and have a tile trim, definitely make sure that the bottom 'sill' piece has a slight tilt to it so that water runs into the shower.Windows inside a shower are always a problem, it's just not a smart idea.
