If breaking even on the front end is critical, these estimates don't leave much room for error. 

And with Maryland's current private septic system laws being what they are, the cost of installation for a new septic system could be very expensive if the property is located in a Bay Critical area. 

Just thinking critically here. 

Make sure that they get you the current zoning, comprehensive plan zoning, adjacent lot zoning, all required set backs, maximum density (how many units per acre), possibilities of development (detached SF with ADU, Town houses, Row houses, etc), possibilities of any critical areas, and any other concerns that they may have regarding the property.

It's also critical to tell your tenants if that alarm starts going off, don't just pull the batteries.

Any but of advice or constructive criticism is greatly appreciated

When they call in the tow truck they then have to wait for the tow truck to get there and see the whole process through... which makes, a what would be 30 second conversation with their neighbors ....a much faster and pleasant way to handle a simple parking violation and turns it into a 30 to 40 minute ordeal along with the added paperwork and enourmous fines that the homeowner would have to pay to retrieve there vehicle from the impound lot..anyone with critical thinking skills understands this defeats there argument that they dont have time to babysit all the adults in the community...I asked them " if your mother lived below you and her car was getting towed.....you wouldnt let her know that her car is getting towed?"...

It's one reason I try not to be too critical of people who want to spend all of their disposable income on status - clothes, cars, vacations, whatever.

Also if you're only looking at it through natural window light, then you might be looking at it to critically.

When you eventually move out and turn it into a rental, you've have a ridiculously low interest rate for the next 30 years on one of your first buy-and-holds that your roomies mostly paid for for the first few critical years.
