I wouldn't put all or most of your investment capital into these based on the simplistic view that you might see 18% annual returns (you should never put everything into a single investment category anyway, but it's worth reiterating).  

It's one of the most simplistic, low-featured database sites out there.

The opportunity for basic investing arbitrage is perhaps better than it's ever been or ever will be again in our lifetimes.Additionally, the benefits of leverage to be able to buy property (or other assets) at the currently depressed rates gives the ability to both dollar cost average and increase cash flow long-term (with the obvious risks of leverage if you use too much of it).Add these benefits to the benefit of the interest deduction (which is much higher than 20% if you're earning more money, btw), and the overall benefit can be extremely positive.Again, it's easy to approach this topic with a very narrow and simplistic view, but good investors realize that most things are not simplistic in this world...

This may be a confusing, simplistic explanation, but you have separate liabilities to worry about and assets to protect.

Tom,You seem to like to take complicated subjects and try to whittle them down into pithy quotes and simplistic rules.

My thoughts - This is probably more simplistic than some may like, but, if you are asking all of us about whether this seems like a good situation or not.................it is probably not. ;) I manage 50 units and have placed 'good' folks in similar situations and have paid the price...It is highly likely (I believe) that your intuition will turn out to be correct.Of course, it makes sense to weigh risk vs reward based on rent rates/candidate pool/current occupancy/etc...But, if I were a gambling man (I'm not), I'd lay cash that the new tenants are late by month 3 and unable to pay by month 6...

In my (overly simplistic) analysis, any property management efforts you're doing are worth $6.73/hour.  

So it is possible that because this was a four unit project that the documents that were prepared were overly simplistic.

That is the simplistic way it happens and it is easy in process, it is difficult to do.

I'll just put an over-simplistic statement out there:YES - 100% financing is possibleYES - interest and other fee's will probably eat up all your cash flow and profit.Over the short-term anyway...Caveat Emptor
