The main attraction for me is to have a "track to run on" as opposed to being attracted to the "next shiny object".  

The rates are very attractive on primary residences, but not worth the low balance (compared to the amount of equity that would be left un-allocated). 

Service offering squeeze pages + optimized PPC campaigns to attract leads to what ever area, you want. check it out!

But the more units he owns, the more attractive the package will be to his buyer.

That could make the whole thing more attractive to a potential investor and could impact my offer.Thoughts?

The laws in Sharjah about rent locking for 3 years makes it less attractive to me personally, but again I can't say much because I haven't studied the emirate yet.

We were forced to quickly learn the ins and outs of the local court, evicting 5 residents, and starting the process in several other cases, prompting the tenants to leave.Key lessons gleaned during the first year were:1)To attract good tenants, you need to have attractive properties.

Truthfully, if you bring this type of deal to an investor, they will self-evaluate...but time is valuable, so a complete scope of work with a comp analysis all bundled up makes the deal initially attractive, which is what you want (what is my cash on cash, ROI, Cap rate, IRR, etc...)...otherwise you run the risk of getting caught up with someone that can't close on the property...if @Richard Francois actually considered taking title to this property, he would be F"*cked rather quickly.

At the time I got these later 30 year loans, the interest rate premium didn't seem attractive enough to go with the 15.  

Generate a little money, then use some of it to...Begin doing low-cost marketing (postcards, door hangers, etc.) to attract sellers, and then start wholesaling yourself.Identify and talk to as many serious buyers as you can, then go back to that established investor or wholesaler from Step 1 and arrange a joint venture wherein you'll help them sell their deals (to buyers you bring) for a piece of the wholesale fee.These three tactics alone could get you learning the business tomorrow, if you wanted!
