Just make sure the numbers make sense on the investment and that you can pay it all back.

Numbers-wise, it doesn't really make sense but it is an area where you can count on long-term appreciation, just not sure it's worth the headache. 

And I sense you are not the type that will waste anyone's time when sharing your strengths and weaknesses. 

But I was only asking if it makes financial sense to do for ROI

Sorry, if this does not make any sense.

For example, we have seen multiple instances of C-Corps set up that made no sense when one looks at the clients' financials, returns, businesses & goals. 

I would start with asking why they want to rent if they have been owning - does their answer make sense?

The list goes on.You can get a sense from that that how you'll manage in a particular area is really defined by a combo of a lot of external things and how you fit your services into the local market, and how to best serve the needs of your clients and tenants.Beyond all of those things, the best advice you can get, if you're serious about building a property management company, is to really think about what systems you want to put in place.

Now question is at what price it won't make sense?

I'm getting a 100k HELOC now and intend to use it for my first rental property purchase, so we are in the same boat.You just have to run the numbers and make sure it makes sense.
