I have several CFO clients that do similar heavy rehab projects in the Midwest (albeit with a lower purchase price), so you can definitely make the numbers work. 

Great question - 20% down is the typical down payment for investment properties, regardless if it's a single family, duplex, tri or quad.We have a 15% down option for the same type of loan.

As another poster mentioned rates are lower than they've been in the previous 18+ months but unless some very surprising economic data comes out between now and when you did your refi it seems unlikely that rates are going up in the short term and there is at least a decent chance that rates drop a little more before then. 

Once we lowered the price to $1 less than everyone in town we filled right up.

I adjust pricing based on demand, like raising rates during peak season or local events, and lowering them in slower months to stay competitive.

If they don't pay willingly, what are my options? 

I was going to do that in an attempt to get creative with my financing options so that there are no liens on it and I could borrow against it as an option.

Have you lowered the price at all?

Question: Should I collateralize the loan (if using private or hard money), or rely on roll-over loans (to maximize the lower points and 3-4% rate)?
