Even after you sign the deal, based on inspection report, you can ask for price discounts - using inspection report as basis. 

Not to be harsh, but as soon as you started to offer discounts and concessions to them, you were screwed.....they already figured out you are a weak landlord and they can walk all over you....sorry.... you set a bad precedent.Now they may have stopped paying rent and bailed anyway, but with your previous behavior, they smelled blood in the water and knew you were ripe to get bitten even more.Best you can do is start the paperwork for failure to pay, eviction and follow the law....recover the property and move on.Its always a dilemma about  going after the $$ they will owe you....huge hassle and you will never see the $$....but you let them off the hook with no record for the next landlord to find out about.....

Pair that with negative discount points for the closing costs, and you're looking at JUST the 3.5% down plus a little extra, and you will still get an interest rate you see advertised everywhere (basically taking that extra X% profit margin the broker's not allowed to keep and using it for closing costs instead of using it for a lower rate). 

Or at least a super discounted price for early adopters? 

I had one just tell me I couldn't opt for the upgraded shingles because my insurance wouldn't pay for it and he didn't get a bulk discount to buy the shingles that I want. 

Pros: Easy to find tenantsPros:  Normally can purchase property at a good discount because of the neighborhoodCons:  Nightmare tenants who will tear your property up and literally destroy it.Cons:  Slow slow monthly payments.Cons:  Hard to sell property , who wants to buy a property in a crime area.Cons:  Dealing with the governmentCons:  Very Hard inspection requirementsCons:  Maintenance of property requirements

Is the price discounted enough to take the future risks into account?

I'd think you would want a deep discount for all potential problems.

You may or may not like that idea.Alternatively, you can do it yourself with any discount brokerage.

Remember, you can always ask for concessions and additional discounts once you're under contract and have your DD period for inspections.
