Basic rehab of cosmetic kitchen/bathrooms.

Although STR can seem sexy and the potential to make more than a long term rental, you also have to consider the start up costs...furnishing, linens, plateware, small appliances, washer/dryer, baby gear, decor, pictures, curtains, televisions, games, routers, professional photos etc etc.Hope this helps a bit, not trying to talk you out of it, just food for thought.

New kitchen, bathrooms, finish basement.

It already has LVP on living room/kitchen floor so pretty low maintenance.

The two apartments needed a little bit of fixing up as well (paint, renovated kitchen).

New construction Apartment Windows/Appliances?

If the property has newer appliances, HVAC, roof, siding, driveway, etc, I will account less for CAPEX - maybe around 5% and if they are old I would account for 10-15%.

I've been looking at similar properties in the area but am not exactly sure what would be a good price with the house being a new build and all new appliances.

While not scientific, a good rule of thumb is if it's a bread-and-butter south city duplex/quad without much 'pizzazz' (think formica countertops, slightly dated kitchen/bath) in a so-so or even decent area - stick to long-term and don't waste your money on the furniture or even slight rehab.

There's lots of inexpensive porcelain that is literally jet printed with stone patterns, I love it for kitchen floors and counter backsplashes.
