It's going to be priced pretty high as the owners have gone all out to make it attractive to yuppies who want to live near DT with quick access to all Austin area hot spots, restaurants, coffee shops PLUS have income from 2 other units to supplement high mortgage payments. 

You don't and shouldn't aim to take someone's shorts -- just provide a good, clean, safe unit at a reasonable price you can both be happy with.

Look Foward to hearing your replies thank you.A quick rule of thumb is that every 10,000 financed right now is about 54 dollars per month on a 30 year fixed if you're considering investment cash out at around 5.00% so that 54 X 12 months = 648 dollars annual per 10,000 obtained at close.This would be considered a mortgage constant of 6.48% annual or payment so whatever you do with this 10,000 just make sure it pencils out because you'll be having 6.48% annual pay out or higher.Personally I try to triple my cost of capital so if its 6.48% I would aim for 18-20% cash on cash or higher so that the 6.48% is only 1/3rd of your annual Cash flow return (obviously there other benefits too like forced equity, appreciation, tax benefits, etc). 

I'm ready to fire and aim!
