The purchase for your property is the reason I constantly state that investors need to look at hundreds or thousands of properties BEFORE MAKING A PURCHASE and the investors need to do the math for every property they look at a hundred times to determine what property will give them the best profit.

Because there is no income verification requirement for many of these loans, there is no real ability to repay other than rent. 

For example, send them a bill for $50 or return $50.

 also, since all three units our filled right now, would that mess with my ability to get an FHA loan?

Remember there are typically 3 approaches to determine 'value' and the sales comparison analysis is only one of the three.

You when then need to determine the expenses on the property such as taxes, water, trash, electric, maintenance and etc.

View reportHello Everyone,I'm trying to determine if this deal is worth my time and money.

When all goes well things are good. 10 years ago, Investors enjoyed working with good wholesalers who would actively scout the properties desired and do all of the leg work.Over time, the ability to get involved with little or no skin in the game, the ability to make a lump sum of money quickly, and a plethora of bad information made available by people who were only after the disposable income of those who really did not have enough money to get involved in higher level RE took a good tool and exploited it.Wholesalers exploiting undereducated layman (someone who does this exclusively for a living is operating as an Agent with no licensing issues to restrain them or cause them to disclose expert status), using a lot of really distasteful tactics (like trying to wholesale deals already on the MLS, co wholesaling through a string of folks) and getting greedier and greedier as they went....That's where the stink came from. 

This would then kill your ability to operate as an REI on that homesite.  

One has a hard deadline otherwise the buyer may lose the home and the lender may lose the ability to provide the loan.
