I was expecting to see a list of names with my name up on this list :) here are some 1.

Welcome to BiggerPockets!

I’m curious to know what kind of discounts did you get?

It generally doesn't make sense to build anything on the land to then tear it down and build something else, unless development explodes and you're tearing down ramshackle to build expensive.

This is what we have recently purchases for both 2 and 3 bedroom homes LG 7.3 Cu. ft model DLG7151W , washer LG 5.0 cu.ft. high efficiency top load washer (no agitator) model WT7150CW. dryer LG 7.3 Cu. ft model DLG7151WThe Cleaners love them and recommend them to their other clients to purchase.

We can't find the next opportunity, have little economy of scale, so I'm forced to keep our reserves high.

Is it possible to sell or refinance one unit to pay the other off completely. 

Quote from @Ronald Rohde: Is this AJ's firm? 

You can use petscreening.com to handle this task for you and ensure you are compliant, but I still recommend you really understand the law so you can answer questions or assist with requests. 

If this is financing for a stabilized property rate carries more importance but rate combined with origination fees, pre-payment penalty and term in which you intend on keeping the loan in place are all considerations which together should help in deciding the best financing option.
