Thanks a lot for the answer, there's one thing above that confuses me.So let's say capital gain after selling is $110kpassive active loss from other investments $20klong-term stock loss is $30k. first scenario: is my taxable capital gain is $110k-$20k-$30k=$60k, so this 60k capital gain would be taxed by 15%.second scenario: (110k-20k)*0.15/federal tax rate=$13,500 ; then it would be reduced by LT stock loss of 30k then the actual tax impact is zero ?

There are some simple things you can do to reduce potential damage. 

There are a TON of programs out there that will pay rent on behalf of your tenant if your tenant has lost their job, or even if they are still employed but they have reduced hours. 

Off market deal, found thru a local agentWill negotiate to have purchase price reduced by 20% How did you finance this deal?

In the short term, shifting strategy to carve outs can reduce risk here or buying assets with likely quicker exits.

Just be aware of the appraisal and if it does not come back at your offer the seller may not reduce the price and you could lose out on the deal.You're also not required to use that agent unless you have signed a buyer broker exclusive employment agreement.

I am loving the commercial space and the reduced head aches.

I think I may have found a property for the hack about 3 miles from me and the price on Zillow shows the it has been reduced from $199,000 to $90,000 so it appears that they are motivated.

If they say they have to see it then find a different realtor.In my opinion, if you can sell the house and make money, or just break even then worst case it will reduce your expenses each month. 

You are exactly right, they can't take condition into consideration, their info is outdated, they can't pull sold prices in non-disclosure states and they go off of asking prices, not just sold, so when someone reduces their asking price the neighbors house automatically sinks in value.
