After all, they signed a contract - technically they owe you all of the rent for the life of the contract, or at least for the time period up until you rent it to someone else. 

On the EXACT same day, the house went to pending status.My question is: is it a violation of any regulations/laws that the seller’s agent put the house back on market and actively sell it while it was still technically under contract with me?

If the answer to your question is yes by a significant amount, then it already makes sense because technically you can just buy in bundle and sell them individually to make a quick profit. 

All contracts are "technically" assignable.

You can use a cash advance to place a down payment because technically you're taking the cash from your credit line and then giving it to the lending institution.

Technically at this point it was a pocket listing.

Can you claim deduction on the interest paid on other units as well , I know this might be complex , but if you understand  these deductions are available only for owner occupants , In this scenario , you are technically occupying only one unit .3.

I tried to get exposure to each of these areas as I was going through school because I didn't know what I was going to need to know until after I graduated and started working (my focus ended up being mostly on the hardware side of the spectrum).When I became too out-of-date to do engineering (I went through school using a slide rule because electronic calculators hadn't been invented yet), I switched to marketing semiconductors to circuit board designers and then became a technical writer documenting how to use electronic products (I enjoyed taking things apart as a kid and figuring out how they worked).

So understanding that is my goal, technically a property that cash flows nothing after setting aside reserves could be an ok investment.

I won't be offended if someone else brings you a deal.There are a couple complications with MLS...so, if you work with multiple agents you'll be looking at the same database of properties...and if you are on multiple auto-feeds or have multiple portal accounts in the same MLS database, the system gets confused and it causes technical issues.
