When working on buying foreclosure properties at any point, u have to realize that u do not have time to fool around, because there is no shortage of people that want to buy a home for $100,000 under market value. The really good deals last about five minutes.
On the other hand, u can buy a really bad deal in a hurry, too, so making snap decisions will cost u money.
You have to know how to check the land records yourself to find all the liens against the property, how to estimate current loan payoff amounts, & how to estimate the cost of structural matters. And u have to be able to do all of that faster than the other people that want to do what you're doing.
In my experience, banks do not negotiate much with buyers. They will sometimes negotiate with sellers, but they r not interested in getting into negotiations with someone that may or may not actually buy.
However, sellers can be hard to work with if they have no equity. They do not like the idea of signing a contract that has them bringing money to the closing table, in the hopes that the payoff can be negotiated for less than the full amount.
Once the bank owns it, it is anyone is guess whether they r easier to work with, or will give a lower price. Sometimes the block to a seller sale is the second mortgage, which is now gone, & u can get a better price. Generally their contracts r so lopsided on the non-price terms that it is actually a chore to get them to the closing table.
It varies. Buying foreclosure properties at any stage is not for the faint of heart. If you're new to real estate, get a really good attorney, as the pitfalls r pretty deep.
