These have their place in the market place, but you just need to understand what you are looking to do and what your strengths and weaknesses may be. 

The typical debt ratio is 50% max except for FHA which is 56.9% and VA which in certain circumstances has no debt ratio limit other than what the AUS or automated underwriting system determines is the max. debt ratio allow based on the individual strengths and weaknesses of the loan file package?

Finally, your tolerance for vacancy and the strength of your local market are of course factors and that's a call you and your partners must make. 

What's strength and trajectory in market for such?

The importance with these deals is to understand the strength of these tenants (sounds like all are small local businesses) and how long they have been in business (I'd feel more comfortable with a coffee shop that's been in the same spot for 12 years than one that's been there for 2 years...). 

What are your strengths?

I'd say it depends on the strength of the cash flows from the property and how much equity you will have at the time of refinancing.

However, depending on your financial strength you may need to wait a few years.

Perhaps in getting someone interested in your deal, you could partner with them - subject to your strengths aligning and their credit, of course.  

From the way they source properties, the way they oversee renovation and ultimately the management, each provider is going to have its own strengths and weaknesses.
