While I agree that the STR market has matured and margins are compressing, I don’t think this is a universal truth especially for Americans buying in international markets like Germany.

@Jim G.Per the International Residential Code if the glazing is less then 60 inches vertically from a standing or walking surface then yes it’s required to be safety glass as it’s considered a hazardous area.  

Very few providers are actually internally sourcing all of their national real estate data—there is lots of copying and stealing.

Adding and making better could sell or rent faster, but it won't get you more than what the market ARV and rent is set at from other similar comps in the area....and your Interior Design background will help, if you you it mostly as an understanding of cost. 

Again, this is a conversation to have with your accountant to ensure the benefits would outweigh the costs.Another misconception is that there is little value in a cost segregation study for properties that do not have a lot of personal property in them or very little interior build out, such as industrial warehouses.

The property is unique—it’s off-grid with a well, solar power, and a fully finished interior.

Spend what’s needed to upgrade with reliable mechanical systems, roof that doesn’t leak, remediate all mold; interior design modernized; in other words a place that will attract a higher income no hassle tenant.  

The Austin metro was among the hottest destinations in the country for where people were moving last year, according to the latest annual ranking from U-Haul International Inc.Austin ranked No. 5 among the top U.S. growth metros in 2024, and Texas was the No. 2 state for move-ins — bested from the top spot after three consecutive years by South Carolina, according to data released Jan. 2 and Jan. 3.The Dallas-Fort Worth-Arlington area took the crown for the top growth metro in the recent list, followed by Charlotte, North Carolina (No. 2); Phoenix (No. 3); and, Lakeland, Florida (No. 4).

House gets foreclosed on when a borrower is not paying its debt obligations - typically its mortgage.buying foreclosures is not for the faint of heart as you have no idea of the interior of these properties lastly while it can be beneficial also realize if there are a lot in an area those homes are the new comps when trying to sell so it lowers home values in an area 

I own property and do interior design for rental and investment properties so I stay up to date from my clients and local events I attend through RE associations and meetups which I recommend.
