I heard about a condo construction that was stopped by the government because they built more floors than approved.

If you can hire a trustworthy cleaner to switch the sheets and do a quick clean then it's worth it, especially because you can charge a cleaning fee.

Also, I can adjust my calendar and pricing, arrange cleaning, teams and task.

First - realize that AirBNB usually makes a lot more money than a long term rental (based on having a good occupancy rate <# of days rented per month>) ... but that all comes with the responsibility of continuous turn-over - where you likely need a cleaning service, etc as a support staff - unless you are going to do that yourself.Second - When looking at renters - the reason many renters rent is that they DO have poor credit scores.  

The house smells like animalsLocal inspection company says house should be 75% empty so there is clear view of floors and walls.

If you trust in this property, the inspection comes back all clean and its truly something you want then there is no harm.

I don't think it's a major issue as long as they are good respectful and clean MTR tenants.

Bathrooms are actually the best to put more money into then the kitchen, because people want a bathroom to feel fresh and clean.

Gutted the home and updated all appliances, hardwood floors, paint etc.

My dad broke up the concrete in just a few locations so water could seep through and drain into the soil, then filled the pool with the cheapest stone and clean soil locally available, then planted grass.
