Hey,Has anyone ever tried to set up loans for people delinquent on their taxes that was backed by their house?

This is not legal advice please consult with you attorney).Consider a step-by-step process increasing the pressure on the tenant with each step while accumulating documentation (which will be needed in Eviction Court):As per the prior comment, first contact the State Agency sponsoring/funding the Section 8 payments and document for them all the issues to see if a resolution can be reached.

But between my broker fee and the lenders fees, it's usually 2-3% of the loan amount.They're ignoring the $7k escrow for taxes and insurance, for example.

If for example a home is selling for $225,000 it will have an estimate of $1,462/month.With 25% down the calculator shows: $1,023 per month Principal and interest $806Property taxes$125Homeowners insurance$92How can I get a better idea of the total including everything? 

Yes, they are. separate meters and property tax bills.  

We both work remotely and are curious about how long we can stay at the rental before it becomes an issue, wether thats state tax implications or perhaps when our jobs should be notified that were working in WA vs OR?

Let’s say we pay X amount in mortgage.My question is : how do I calculate mortgage/interest/property tax for other house which we have rented so that I can deduct that from rental income?

If you expect to have $2mil to invest and need $160k gross (120k net assuming 25% tax for sake of example), that's an 8% pre-tax yield. 

It would be same as saying you also owe future taxes and insurance.
