There's a lot of inventory out there, but triple check your numbers before making a move.

Triple Threat...Wife, Mother, Employee.

@Jay Hinrichs EPA is still up and coming :) I sold my PDX house and it's more than tripled since (ouch)

So, about a deal a month.For organic, you can triple that number (again, assuming someone's putting in the effort and so on).

I would not want to install that in a bedroom, as that would signal to any potential future tenant or buyer that this is a very scary neighborhood, where you have to double and triple lock everything.

Commercial locks almost triple in price compared to residential locks.

If not you can walk away.Here's a specific clause that I have used in a similar situation:------------------------------------------------Commercial Tenant/s Requirement: Buyer shall have thirty (30) days from acceptance ofthis Offer to Purchase to identify one or more qualified retail tenants for the subjectproperty or this offer shall, at Buyer’s option, be null and void, and all earnest moneyreturned to Buyer immediately.A Qualified Retail Tenant is defined as a prospective tenant who (1) has profitablyoperated a similar business to the one proposed for the retail space for at least the past 3years, (2) provides reasonable evidence that he or she can obtain or retain any necessarylicenses or permits for the proposed business, and (3) signs a Letter Of Intent to (i) rentthe ground floor retail space of the property for at least 3 yearsstarting in 2014, (ii) pay rent of at least $20 per square foot per year Triple Net in the firstyear with index-linked increases for the remaining term, and (iii) pay for any constructionor modifications required to operate the proposed business.Seller or Seller’s representative must be present during all showings to prospectivetenants

Make a 'triple crown' in that room.

Maybe a commercial property with a 15 year triple net lease.Please take my advice, pay enough down where it will easily cash flow. 

15 years from now your 800K house will at least double if not triple in price.
