Is this a "housing project" for low income renters that may scare away some home buyers / renters and lower property values and rental income around it?

I dont want to low ball it and then have her slam the door in my face.

We were fortunate to be able buy it low enough that we can afford to do this and still make a significant profit. 

Someone has done something similar to what I want to do - building new mixed into an existing neighborhood - with five homes all side-by-side that average over $100,000 more than the existing homes in that area.Some of my questions are:Is there reason to be concerned that existing homes in the neighborhood have low values because of their age and condition, keeping in mind I want to build 9 or 10 and raise the level of the neighborhood?

Rent is 1300/month which is a little low for the market.My current loan has 19 years left in term, Montly P/I payment = $860.83, rate 4.85% annual adj.

I am glad because of the LLC added protection, low monthly mortage because I put 25% down(which i found private money on).

That is how you can end up going from $650 to $2k.The maps for NOLA and the area were recently updated to reflect all the Post Katrina improvements, so right now, the rates are really about as low as they ever have been. 

However, rents are low in my area, and wouldn't cover my current mortgage.

Construction Loans:HELOC's are great for their low interest rate.

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