There are positives and negatives with each and you must have the right abilities, team members, and systems to pull them off successfully and consistently.

Seems like a negative, but it's not.

This agent really did respond negatively; however remember not all agents are alike and there are some really good agents that go above and beyond in regards to doing their jobs and actually we work really hard for the money, but the agent was definitely out of line.

Am I just being overly negative or justly cautious?

I have tried to crunch these numbers and I'm getting a negative cash flow on this property.

I typically use 10% for repairs/maintenance, 10% for property management (you still want this in your analysis because if the numbers are still good, then the deal is great), 8% for vacancy and 5% for CapEx.If you account for these expenses (not sure if you're including utilities or not), your cash flow goes negative in this scenario.Additionally, is your investor only getting the mortgage payments?

This means the actual income from the  property is negative not positive.

Market rent in your area will be negatively impacted.

But that $20k just turned to $0k (or even negative!).
