Wow, debt of 50+% assets is 'fine'?! Grab the nearest person who lived in the 50s, and ask them what they think of it. That we've grown accustomed to this sort of debt is the cause of all this mess.
Even if you owned nothing else, and had no other debt then a standard 80/20 mortgage has been considered a good deal all around for decades and still is. That's 80% debt to 20% asset at the time you assume the mortgage. Yeah, I'd say a 50:50 debt/asset is OK. The bigger concern is cash flow as shown by Debt to Income ratio because it speaks directly to your ability to service that debt.
