When I say quality, a quality person renting a sub quality place isn't happy, if they have a situation like a foreclosure through four years ago and they want to be homeowners again, they should be willing to jump through some hoops as far as rebuilding your credit historyAlso I mean quality is far as the quality of the location and the quality of the house that's for rent, many houses for rent are crap, and the best school districts and safest neighborhoods are only houses for saleCharles I've been doing this for 30 years and with the times that we are in right now with tenants having such a hard time getting a mortgage and getting out of the Rent  Trap, this is not a buy-and-hold strategy Like in stocksI live in a very expensive area Los Angeles and the average person can buy house because they're 900,000 to 1,200,000 where I live and lease purchase has a place here because many people can get mortgagesBut if you lived in Pittsburgh or you live in Cleveland or you lived in Orlando, you can make money with lease-option assignments or sandwich lease options if you've got a little bit of money for reserves as a real estate entrepreneur operatorWhat's in it for the seller is they can lease with an option hopefully with the right screening of tenant buyers that have ties to the community and strong employment where they're  not going to lose their jobsWhat's in it for the investors is that they can do a lease option assignment or sandwich and make some money without getting a bank loanI do like lease purchase over lease option for the seller because it's a stronger commitment and a definite end to the dealFor the buyer I'd much prefer a lease with an option with an extendable option in the initial contractFrom a business point of view if you're interested in getting better appreciation you can just do one year agreement and ratchet up new agreements at 5% a year or a new appraisal every 12 monthsI have put together a lease purchase arrangements where the sales price has been tied to either a new appraisal or a set floor price whichever is higher, to prevent a loss; in stocks this is called " collaring "where you have a  call order at a lower price to prevent a big loss and an order to sell a certain high priceSee protective collar http://www.investopedia.com/articles/optioninvestor/07/protective_collar.asp

The work is performed in an environment similar to asbestos removal (filtered negative air pressure).

& "tenant is responsible for heat, electric and sewer bills"For the heating and cooling information it mentions that the property has oil hot water, gas heating, forced air heating, and zoned heat. 

The only thing that would prevent you from that is if the property is held in a retirement vehicle.

If a house has gas air, does that not mean that it is essentially piped for gas heat and you could make the conversion?

Central Air Unit became operational.

Essentially it stipulates that they will assess the risks of back flow at my property and determine whether or not a back flow prevention device is required.  

If it's a single family house, you likely have no grounds to prevent them from holding a birthday party in their own backyard or having children over.

I would like to prevent calls in the future.    

The owner put an addition( w/heat/air )Because it still has the metal frame banks, conventional/fha .
