Things like wood-rot, or if the bathroom is being renovated, etc. will be flagged for most loan types as things that need to be fixed before closing. 

Harb, it is a bit like asking how much for a red car!

How to quickly determine what is worth their time to invest on and how to pick out RED flags. 

@Stephanie Ferrante, 15 Cap is a huge red flag to me.

first you have to find ones that will work with foreigners.Peak in KC will I believe Lima ONe willalthough keep in mind real estate lending has been in fested with FAKE lenders and scammers.here are the red flags:1. interest rates far lower than market like 4 to 5%  this simply does not exist in the market place they just are sucking you in thinking you found this unicorn lender.2. reason they can lend that low is you buy insurance to guarantee payments.. this also does not exist its a fraud.. there is no such product.. 3. offer to show a picture of the person your talking to holding their ID.. again just smoke and mirrors.4. tell you what you want to hear but need 500.00 to 800.00 deposit to go further.. you send that you lost it.5. bad webstie or no website.. poor English etc.

If so, that's a red flag.Why is this property going into foreclosure?

I am sure it doesn't matter to you, but the way your friend runs his business is definitely a red flag. 

If the owner doesn't have this information or unwilling to provide, first that should be a red flag and secondly you can do what I do when I'm shopping apartment communties, go secret shopping meaning show up to the property and pretend as if you are a potential tenant and find out how much they are paying in rent/deposit.

With unemployment just under 3% and continued votes of confidence by employers such as Apple, Oracle, and others, analysts believe that the Austin area is one of the top housing markets to watch in 2019.Steve Crorey, 2018 ABoR president, once again flags affordability challenges and their effects on the market: "Families and young professionals continue to move to the suburbs where there are more opportunities for home ownership at a more reasonable price point than in the city of Austin."

@Joseph CharlesYour one comment here concerned me:  "I can run up the number of properties very quickly"That is a red flag for failure.
