@Noah Margate, if I get seller financing, I don't have that mortgage show up on my credit report, I can negotiate the interest rate with the seller, I do not require an appraisal, origination fees and other "junk" closing costs. 

We've found it has superior reporting features, integration features, and is overall more efficient to work within than other REI-specific software.The downside is QBO is not set up for REI so you'll need to do that or work with an expert to ensure it is set up for your business appropriately.Something else to keep in mind is your entity structure and how your entities file tax returns.

Any idea on what would be the per sq foot construction cost for this project?

This covers the purchase price of the property, any required down payment, the cost of the renovations, and any other costs like holding and closing fees.

This would in-turn increase the building value.I have identified total costs and time for this potential change, and was curious what resources or anecdotes you may have to analyze the cost of the zoning change vs the residual outcome and lift in value driven by an increased buyer pool.

I work full time (own my own business and can be somewhat flexible) and I am about 3 years from retirement.

Again I'll do more research on how much this could cost but I imagine it wont be cheap.

What if the IRA owns a fund with the S&P 500 and it is impossible to live in the US without doing some business with an S&P company; prohibited?

I suspect a pad for a vehicle can be provided at fairly low cost (it could use gravel instead of hardscape).To compound the parking issues, the city has been taking away parking spots for dedicated bike lanes.  

But also weigh the alternative of how costly the prepayment penalty is.
