School districts are average and household income is above average compared to Ohio averages.

Renters are comparing other units to yours, I would guess central air would account for $50-75/mo in lost income overall. $1700/mo x 12 x 20=$408,000 - $1000 for window A/C units= $407,000. 

I am about to purchase a duplex.I was informed that it had meth in it, but was cleaned and certified for good bill of health.Does the fact that it has had this issue hurt value when compared to similar duplexes in the same location that have not had the issue?

What would your competitive advantage be using shipping containers compared with the competition using aluminum buildings with garage doors, a retail office, security gates, etc.?

I would be curious to know how many investors are really purchasing residential real estate deals with owner financing...The idea of owner financing in the context of a residential property has always seemed to me to be a bit of an urban legend; something promoted by so-called gurus to new investors hoping to get started buying deals with "other people's money" and no capacity to get a loan from a traditional lender.Let's consider the the most basic version of owner financing:  Buyer agrees to purchase property from seller. 

I have considered designing all 9 or 10 homes and "pre-selling" based off the renderings and floor plans I design, to at least sell a couple to prove the idea before we break ground.I want to work directly with private investors, not traditional financial institutions.

A comparable park I analyzed last week has a similar well/septic combo had an actual septic expense of $1,200 (this is low). 

Heart of the Question: Do traditional lenders REQUIRE actual cash, or can equity in home count?

Most of the time the banks here don't even order a walk-through appraisal, they just send someone to drive by to make sure the house actually exists, and then us a formula based on comparable sales to decide if it's a go or not.

My husband and I are working hard to find a lender that will work with us, however he is self employed and starting flight school (which requires a large loan) and my income alone will not qualify us for a traditional loan in our market.
