Travel nurse demand is down quite a bit so I wouldn't just count on housing traveling medical professionals. 

He still hasn’t moved in because of some medical issues (as per him) and hospital admission  etc etc and saying will move March 15th now.

for 1050/month all bills paid. they claim this cash flows 3600/month (4200-600). the math on that is they say electric is 90 unit, trash and water is 50 each for all 4 so theres your 600 and say they can provide receipts on all this. it's located  a handful of miles, about 6-8, outside the nearest small town with a wal mart etc.one thing is it seems better apts, in town with 600-800 ft, go for more like 1k no bills paid. even adjusting for the all bills paid part, i feel like 1050 is aggressive on these. otoh near me some crappy tiny apt with mold and everything go for 750, and these are much nicer than that. i think 700-800 would be an absolute floor on what they could rent for.i guess i just have no idea for example, insurance?

More commonly, 4-star properties have seen as much as 200- 250 basis points of expansion.This range of cap rates is generally found in the upper 7% to 9% territory, indicating that office property values for transactions over $10 million are down by roughly 35% from the all-time high in 2021, excluding medical and owner-user sales.Debt maturities pose challenges for 2024, with around $206 billion in office loans maturing this year and another $180 billion in 2025 and 2026 combined.

I'm about to start short term rental for travelling Nurses (travelling medical professionals).

How close is the nearest grocery store out of curiosity?  

I own MTR's in a San Antonio medical center and I can give you this advise: Traveling nurses/professionals are looking for small accommodations (lower price point), they are concerned with safety, as they are usually women traveling alone, well-lit walkways by their parking spot, private entrances/bath/laundry.

2/1s  and 1/1s are great for travel medical professionals and digital nomads. 3/1s are a lot tougher to rent as MTRs.

Since I was a medical student, I've always been passionate about making smart investments for my future, and real estate has piqued my interest for its potential to generate passive income and build long-term wealth.

Just like medical, e commerce, or real estate brokerage.
