I do not do any flat rate to the tenants I just bake it into the rent! 

Do you let the tenant supply and pay for their own internet or is it recommended to offer internet and charge the tenant a flat fee?

(FWIW,$8K on just the compressor seem excessive.)Otherwise, unless your contract with your GC says they will provide 24/7 surveillance, or you can prove the AC was never installed, you own the problem.If the property has been vacant for more than 30 days, most policies won't cover vandalism unless you have added a Builders Risk Addendum.

I think $1,700 might be excessive but I've rented out a room for $800 beside, so that x2 should've been my starting point at least I think. 

Quote from @Joseph Alfie: Quote from @Sean Graham: I have a 3 flat near 67th and Jeffrey.

It's a 3 bed 2 bath on an acre flat plot.  

My excess cash flow per year is around $300k in cash, meaning theoretically I could do 6 deals, but in order to make that salary (HHI $722k) I need someone with the time to do the repairs and manage the tenants.

They act as a fiduciary, and they charge a flat transaction fee regardless of investment amount.

I did just this in my two flat, it cost me around $150k to rezone, dig down, upgrade everything plus fee after fee after fee and materials after materials.

Rent growth has been flat over the last year so you need to account for flat rents near term.
