Personally speaking, from an investment broker and investor standpoint, I feel single family investing is the riskiest in some investment ways in comparison to larger investments due to the fact that it only takes 1 repair or tax/insurance hike to put you under or lose all income.

If it is to cash flow right now, then you're right you would be a little tight with your tax/insurance escrows.

My payment with insurance & taxes is $1425 a month.

A refinance into an LLC avoids this risk but typically requires a commercial loan with higher rates and stricter terms.If asset protection is the main goal, umbrella insurance may suffice without disrupting financing.

Right after I closed on that one the insurance company demanded I make a couple thousand dollars of repairs.
