The Supreme Court has recently ruled that the second can not be wiped out if under water.
Go to Pacer.gov and look up the BK filing.
Also don't forget that if you foreclose on the 1st CA allows 1 year right of redemption so if you get title to the house you are in limbo for 1 year.
If you pay more than 20% of UPB you are paying too much. Don't put yourself in the position of a bidding war. Do not be attached to the outcome.
I have a VA call finance companies within a 100 mile radius of where I live and ask if they have non-performing paper. It is a gold mine if you are persistent. Why because no one else does it.
Right now I have a car note paying 92% yield that I bought. Had a GPS installed so if the payor is late then by my iPhone I disable his ignition. I then no longer have payment problems.
Don't follow the heard. Be like Warren Buffet look for deals where no one else is looking.
Have the seller pull a 3 bureau credit report on the payor and see if he/she has the capability to pay the second. What other debt obligations does the payor have? Most people buying non-performing notes do not do their due diligence.
These are some of the things you need to know before buying the second:
Credit score of payor
Place of employment
Yearly income
Other real property owned?
Any pending lawsuits?
Are property taxes current?
Check municipality for code violations
Unfortunately all you hear about all those that made money from NPL you never hear about those that lost their shirt.
Go to Amazon and read Gordon Moss's book on seconds.
