If you haven't gotten a response, it could be because the numbers don't work.Here are a couple of tips to help your post get noticed:- Post often!

I noticed that in my city, there is an area of town known colloquially as the "ghetto". 

When a tenant gives notice they will be moving, we will meet with them in the apartment/house to go over the move-out instructions.

To me that seems frequent enough for them to take notice to your mailings but not too frequent to where it would start getting really expensive.

The other thing I noticed is it's listed as owner occupied on the county assessment. 

. - I did notice an airport nearby, so possibly the property is 'centrally' located.- From a street view, going up and down the blocks, I couldn't tell if this property is in a highly dense location, or just simply located in the projects. - 1 Bedroom / 1 Bathroom rent is 500.00Look forward to thoughts and opinions 

Closing costs on both the sale and purchase also factor into the calculation.1) purchase price plus your closing costs is your initial basis.purchase price $100,000.00purchase costs $2,000.00initial basis $102,000.002) depreciation reduces your basisvalue of improvements $80,000.00annual depreciation $2,909.09depreciation after 10 years $29,090.91basis after 10 years $72,909.093) closing costs on the sale reduce your net return from the saleselling price $150,000.00selling costs $3,000.00net selling price $147,000.004) net selling price less your basis is the total gaintotal gain $74,090.915) the gain is now split into unrecaptured depreciation and capital gainsuncaptured depreciation $29,090.91cap gain $45,000.006) And the tax is computed on eachrecapture rate 25%cap gains rate 15%recap tax $7,272.73capital gains tax $6,750.007) add them up to get the total tax billtotal tax $14,022.73Do notice that each year you had a deduction of just under $3000.  

Also notice that they are not appropriate for SFR's.http://www.propex.com/C_g_capvs.yld.htm

If you have the borrower's SS# and loan #, that may be enough to generate the payoff demand.If the senior lien goes into foreclosure (after the notice of default is filed), I find the foreclosing trustee services to be better (and faster) than the lender at dealing with successors-in-interest.  

I'd explain your dilemma, ask if it will be a problem complying with a no smoking policy, then maybe compromise if they say they won't stop, like you'll take it month-by-month with them, but if there are any complaints about their smoking or it's causing problems where other units feel they can smoke, too, or preventing people from living there to avoid the smoke, then you'll have to give them notice to leave, no matter how much you'd like to accommodate.
