I have not set up internet or any other utilities, as there have been no tenants living in the property since I closed in late February. 

So, as a technology entrepreneur, I got to wondering if there's a way to research, acquire, and manage my deals more easily using the power of artificial intelligence (AI) or some other internet software.I have an idea of what I think I need to build, but before I build it, I would appreciate some feedback from this community: What's the hardest (or most frustrating) part of real estate investing for you?

Its all over the internet, so easy to find. 

And doing it on the internet is crazy.. granted some good CpAs have chimed in.. but you need to spend some money and get these answers from an attorney who specializes in these and then a CPA who understands how to set this up as well.at least IMHO.. pay for top notch advice it will be worth it in the long run. 

And I agree with that statement. your second comment on Collusion is not cool and is illegal.. that's all I was pointing out.. you never stated you did this personally and you would be foolish to do so on the internet :).And there are TON of beginners here on BP they read your post the next thing you know there down at the sale trying to collude thinking its easy money ..

Use the internet to find properties, set your goals, and educate yourself.

Once you have more than enough income stream from the US, taking some riskier gambles abroad may make sense.

Whining about the internet you provide free as a courtesy?

If the rent of that 2 bedroom was $1600, that person would expect to pay $800 rent and maybe another $250 for electric, water, heat, internet for a total of $1050 all included.

Considering the fact that you already have a lot of equity locked into MFH that's essentially sitting at ~5 caps, I would think about diversifying a little bit and try to pick up some decent quality C SF housing that is a gamble on appreciation but can have some stronger cash flow.
