I did check Loopnet and it's all listed for sale by brokers and agents, so I don't think it is off-market -- right?

It won't be 100% accurate, but it will be close enough.

You cannot close an RE purchase or sale without using an RE attorney.

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

My duplex - built 1989, 2,060 sf, 2 bed/bath, 1 year old roof, value if I subdivide (county already approved) and sell each separately $150k each ($300k total)Investor duplex - built 1995, 2,300 sf, 2 bed/bath, 5 year old roof, value around $310kThe investors initial request was for an equal trade and they would pay realtor fees, which I replied wouldn't be equal due to buying/selling costs (recording fees, title insurance, closing fee, survey, inspections, loan fees, 1031 fees, accountant fees, repairs), taxes would increase due to new sale price, I'd trade a 3.75% mortgage for a higher one, and I'm on the 10th year of a 30 year loan so resetting that to a new loan would restart amortization and pay more towards interest.

You really have to learn the neighborhoods or work with a sales agent who does.

Quote from @Allison Littman: I am currently trying to close on a church in Nashville (residential R6-A zoning) and convert it into my primary residence.

Home sales hit their lowest level in almost 30 years, so it's not unusual to see a property sitting on the market for many months.

That can be a tough part, but isn't close to half of the process.

Average rental rates, vacancies, competition, growth, appreciation, etc..Ive heard of scrolling through Zillow and collecting information by looking at properties for sale/rent but was wondering if there is a site where all of this information is easily accessible or any ideas for better ways to go about it.Thanks in advance!
