I always advise to run a business for 3-6 months without an entity to see if it something you are making money in and something you want to continue doing.Once you have 3-6 months of activity, you have more information to provide to an accountant regarding income so he can provide suggestions on entity type.Best of luck

I can provide him with an online log in so he can review the books from his office.

Personally too, I look for the best quality and always provide that to all my clients.

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)

I have used avail.co in the past with great success but it appears this software and others no longer market on zillow which I know to provide a lot of leads in the past. 

What are some cities that might provide cash flow, but remain affordable?

There are some that provide coverage but of course the premiums and higher. 

(Even went beyond the second page of Google.)I have an investor who wants to partner on a deal by providing a loan for the down payment.

I'm looking for the cleanest & most visible way to access payment history, see amortization schedule, tax documents, etc- much like bank softwares provide. 

I can’t think of an expensive subscription that doesn’t provide an app.
