You may want to make an introduction between your CPA to those 2 colleagues.The CPA can go over their services and pricing to your colleagues.I partner with many people on real estate deals - It never gets to a discussion on whether they do their own tax return or hire a professional.If a partner mentions he will provide capital - does he provide the capital on a timely manner.If a partner mentions he will find deals - does he find many deals and provide an analysisIf a partner mentions he will manage a property - does he manage the property well(find tenants, collect rent, communicate with contractors, etc)
