I was trained in Internet and Network security and that is a classic example of a scam post.

For example, you set up key word alerts. http://www.biggerpockets.com/alerts

For us, it has been less of a cost of money and more of lease writing in making sure the tenants know their responsibility (for example, snow, leaving heat on to not freeze pipes, etc)

For example, suppose a tenant has damaged beyond repair an eight-year-old carpet that had a life expectancy of ten years, and that a replacement carpet of similar quality would cost $1,000.

@Gloria Mirza75% of the rental income is only used if the property was recently purchased, for example you bought the rental home in 2015, but since tax returns are not due until April there would be nothing to show for it.

For example, you can have money to purchase a few properties right now, but eventually, you need to sign a contract, or more importantly check on your properties.Good luck.

Just are examples of what you can do with excel.  

Take, for example, a home priced at $100K which might be typically be purchased with an $80K bank loan and $20K down.If the seller doesn't need all their money at closing, you might be able to get a $50K bank loan, still put $20K down, but create a seller second mortgage for $30K.

For example if my wife has a self directed 401k could she loan money to say my mother?
