Also, I really wanted the units to be up to my standard, but I think I spent more on them making them look better with upgrades, etc, than I needed to.

Is this structure standard, though, in terms of capping investor returns at 12%?  

And by DSCR loan, I'm thinking standard 30-year DSCR loan.

Hard money and standard loans (Conv, DSCR) are unlikely to be available for deals under $75k.

If you have a good insurance broker, you should be able to use a more standard policy though.

I can certainly handle the bookings and standard service things, but the challenge right now is finding a cleaner who isn’t so expensive. 

STR standard depreciation is 39 years @Andy Lanyi@Jonathan Cooper even if you take Bonus Depreciation as @Basit Siddiqi highlighted the remainder 40% will be prorated using the Half-year convention or Mid-quarter convention used in line with what you read in IRS Pub 946 

@Joy McQuearyRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

This is standard practice, but there are exceptions.

This is because the envelope of the home was not built to modern standards and making functional living area can be challenging unless you have a lot of real estate to work with.
