This site is an excellent source of information.

BP is the only source I know of that provides such a vast amount of free RE information from so many seasoned investors lending time and talents.

Property Management companies sometimes have arms of their company that can help in sourcing properties, rehabbing if needed, then tenant placement.

So you say I can get that info from list source?

As you've probably found, it is a great source of information.

30 days ago , I order 1200 yellow cards from yellow card.com , I obtained the list from listsource.com , here is the result I got 70 returned cards due to inaccurate addresses so far , about 10 total calls, I meet only 1 seller in foreclosure, she was behind 12 month in payments, her house need 40 K for updating, ARV 170. so there is not enough spread , not only that the seller want 80 K .listsource.com provided me with :1) absentee owners with 100% equity ( 500 cards) : these owners are not motivated as much as I thought, many of them want 100% market value, not wiling to consider seller finance of any type, or telling you the least price that they can accept. they want me to give them offer since I approached them to buy their property.2) pre foreclosed list with 40-50% equity (out of 700 cards) : only 3 responds back.the result is worthless while it cost me about $700 for the total of 1200 cardwhat are the best source for accurate listing?

Looking at buy/hold, we talk about about the 2% rule (or said another way, price to rent ratios).So, are there sources for comparing things like distressed vs. retail pricing, or price to rent ratios, across geographic markets?

Make sure you read from several sources.

If those properties are really making you good money, it is probably best you fix the problem at the source.

You will probably get further ahead spending your money on good books and spending time sourcing out other investors and learning what you can that way as well as here on bigger pockets.The best way to learn ultimately is by doing.Best of luckDave
