Don't want to clean up all the tinfoil   ??????         

I was like Wow why no debt returns are better.. well turns out big family that were billionaire developers in Tokyo and they got their clocked cleaned when Japan melted down had to much debt.. took what cash they had ( which was still 100s of Millions) and just paid cash for all their real estate.. they have quite the portfolio.. 

With partners involved, make sure to keep the books squeaky clean so you don;t run into issues down the road. 

I'd have each ensure the place is cleaned before and after use.

I am guessing you don't clean their apartment either? 

Also in the Agreement they charge me 1% extra just to keep the place clean and on top of that I charged separately for that.

Make sure everything is clean, look in cupboards, check the oven to make sure it is clean, turn on elements to make sure they work, check toilets and sinks/tubs to make sure everything works, windows/doors/cupboards. 

People love hardwoods and if they are clean and smooth they are very forgiving about any "character flaws" such as old water stains or cigarette burns.

...Monthly student loan payments (If this is your wife make sure it's not in your FICO report)Monthly personal loan paymentsMonthly debt consolidation loan paymentsMake sure your credit report is clean and no old accounts appear as active.

But I also write offers with no contingencies (cash, no inspection) other than clean title, and relatively high earnest so I would not put an offer in on a house without seeing it first.
