Eric,Without going into too much detail on each line item, at first I use my back of the napkin method with a 40-50% expense ratio.

As far as the business card is concerned, to me personally I think having both things on one business card is acceptable .  

Generally yes a HELOC will go off your personal finances so qualifying is generally based on your income, liabilities, and credit. 

@Chris Seveney I only get payoffs on loans I did not buy at a discount. 

.- at year 7 if value appreciated a lot, can i do a HELOC on it and use that HELOC to pay off the balloon - probably not due to lien being secondary etc on helocYes on the HELOC, but it would probably be easier just to refi and pay off the seller, and cash out more money too.Hope that helps and good luck!

It also depends on how you hold your properties; LLC, S Corp etc... as to what the agent will recommend.

I think it's very dependent on the property and market. 

Rents in the area are strong, do you think it makes sense as a rental, or would you go all-in on the flip? 

I almost forget about this motel sometimes as its our furthest away investment and the manager does an ok job so we don't have to micro manage, although if we paid attention to this place more, it would probably boost our bottom line.

It really all depends on the lender!
