What to buy for next property???

[William Rutledge]

Looking for advice to streamline my Real Estate Plan and purchase of next property.

Situation: Currently have two rental properties. Property 1 is a SFR cash flowing $400/month with a conventional mortgage of 50% LTV. Property 2 is a Vacation Rental Townhouse with cash flow of approximately $200 with conventional mortgage at 75% LTV. I have access to 200k cash and an 85k HELOC. Conventional financing is not a problem thanks to high income and great credit score. I am looking to build my equity position more than need cash flow. I also "Do Not" want to actively manage property. My thoughts are to keep buying property for the next 5 years and then work on paying down debt for that 5 years after that. 10 Year Plan buying 2-3 properties a year would put me at 10-15 properties at end of 5 years. I also consider cash on cash return a very important measure of my investing success.

My question: Should I stick with conservative SFR or jump to MFR with higher cost and greater returns.
