More important question now is: How much equity does each home have now? Depending on how many years you have own each property, maybe it is time to assess them: their individual performance, ROI, what type of tenant do each attract? and what is your ROE (return on equity?).
For recent purchases: less than 3 years, you probably have to grow with them and think about how can you maximize returns: maybe ADUs, or Coin-laundry or e-pay, renting space on the property for storage, air b and b or mid term rentals, splitting the lots, Tic sales etc... or value add to increase appreciation faster!!
For properties you have owned for more than 3 to 5 years +
Take a look at what is performing and 1031 the problem children... :)
For some, I imagine you will have more than $200k sitting in them as "potential equity"
you could sell 2, 3 or more of them and now trade them for a 6 or 10 + unit property. Increase your cash flow and wealth and reduce overhead and management time.
Many of my my investors started with 2 or 3 homes, used a value add strategy , and renovated or added adus or sq footage, and now 1031 into a 6 unit property with the same amount of money, but now going from about $1,500 cash flow from 3 properties to a 6 unit property that now gives him $3,500 gross profit.
Now he re-started buying single fam. homes which are less costly to buy with 5% down owner primary loans. Buy, live in it for 1 to 2 years and then rent it out to buy the next one!
Good luck!
