You should keep a 10-20% margin per clean depending on the market. 

This provides wiggle room in your operating budget and when executed on properties with strong margin, you should be able to pull all of your cash out and repeat.

I can't tell you how many investors I have spoken with that chase low margin apartments and they want nothing to do with Commercial because they know nothing about it. 

Worst case, figure out which one has less risk and more upside, take that one and offload the second to someone else for a fee and you still get a return on it even if its marginal in comparison.Personally I would offload the family one to avoid that cloud unless you can for sure do them both.Good luck!

We were interested in the condo deal with Cindy and Damon Robbins due to several key factors: High Profit Potential: The purchase price of $294,500 and the sale price of $634,888 offered a significant profit margin.

We were interested in the 6th St E deal in St Paul, MN, due to several factors: High Profit Potential: The property offered a significant profit margin, with a purchase price of $135,000 and a sale price of $265,000.

We were interested in the Mount Zion Blvd deal in Ellenwood, GA, due to several key factors: Profit Potential: The property offered a clear profit margin, with a purchase price of $165,000 and a sale price of $234,900.

The bigger the margin the better chance you will do well You are not getting " value add" for the reasons I mentioned.

If the home is old, lots of trees, and the deal is marginal, I would get a sewer line scope.

These are tight margins.
