@Roberto Rodas, I would argue your biggest expenses are going to stem from capex items and tenant damage.  

I have a professional maintain it, and it is a charge (in the rent) not a line item so it's 'included' as my LTR is also in an HOA and I do not tolerate lazy/ non compliant tenants.

The issues on the inspection report were few and mainly related to safety which speaks to the quality of the rehab that was done (e.g. no expensive CapEx items). 

You're going to want to follow the following general rule of thumb:- 0.5 mile radius- same zip code- Sold in last 3 months- Same unit count- Same bed/bath count- Same square footage(this is not fully exhaustive but they're the big ticket items)If the appraiser selects comps that are closer matches to the above than the comps you want to use, you're going to have a tough chance arguing for the usage of your comps over theirs.

I am a subscriber to the Playlist Beta memberships and would like to access the bonus items. 

What's somewhat interesting to me is that there is not a line item for survey.

(This should be cheaper because no personal items are insured.) and then insist the tenant’s get renter’s insurance.

The three items above along with setbacks, landscaping and storm ponds if required dictate your footprint.Find out what the DOT's variance process is and follow that. 

At that point, start stabilizing the properties, proactively spend some cash on big ticket items (roof, furnace etc. that you know are coming due) or upgrades, then start paying them off.
