A lot of research and studies have come out around high paying jobs make large impacts. 

Hey BP family, I'm currently trying to help out a family in need from having to foreclose on there property by taking over subject to, it has a high interest rate although the entry is around 20k I want to wholesale this ultimately Is it possible for me, to disregard my initial assignment fee to get a buyer asap and add a 2nd lien on the property as my fee? 

Sometimes they forget to tell you that many tenants in Detroit don't pay (depending on the property manager skill and the type of tenant) - but taxes are very high in the city and so is insurance. 

I don't know how difficult of a task this would be, but suspect it would make for better quality forum content. 

Highly recommend

The other areas you mentioned are too high for this particular need

I'd keep 70% as a base and shoot for 90%+ on the high end.I think I'd be pretty happy with 90%. 

If you really like the place but you feel that it is priced too high for your budget, instead of saying “it’s priced too high” and insulting the seller, simply say “I absolutely love your place; it is exactly what I want, and I’d really like to buy it.

Even though the nightly rate is high, the RE has such high value that the margins are fairly tight.  

Again even if you have great credit as you start to add more credit cards, mortgages, auto loans to your credit you can also be viewed as "High risk" due to Excessive trade lines in credit or higher DTI - debt to income ratios.
