When I want a tenant gone, I am flexible and tell them they can leave any time in the next 30 days if they give me one week of notice, then I will refund any unused portion of rent.

Yes - this is going to vary from lender to lender but a portion of DSCR Lenders do lend to foreign nationals. 

Not only is it not too much of a commute for most renters, it is actually a preference by a sizeable portion of the rental pool.

Trying to understand the advantages of NV vs CA portions of Tahoe, any insight would be appreciated.

Seller could be awarded legal fees for the lis pendens portion of the case, which you could be held responsible for.

I personally know several families with spouses and children that rent out a portion of their home (finished basement/private entrance room, etc.) that offset their mortgage substantially.

As long as you have a primary housing expense (either renting or own) you will be able to use 75% of the appraisers opinion of the future rent. and you will be able to add back a decent portion of your paper losses on your tax returns for the properties you already own using this form:  https://content.enactmi.com/documents/calculators/Form1038.C... 

(To qualify for section 121 tax exempt on portion of sale.). 2) what do you think your net profit would be after selling costs?

@Ko KashiwagiYes, without the Triplex' mortgage, or if at least a portion of its rental income can be counted against the payments, my DTI would allow me to qualify for the amount I intend to borrow for the new primary.

And if you purchase such condo, you either negotiate the assessment with the seller or take on the remaining portion due.
