Now, I've decided to jump in with my first post and would like a second opinion on a negotiation.I own a duplex literally around the block from the current target so my assumptions are based on experience from that building.  

I just don't want to put the property under contract with bad assumptions/numbers.

You find two or three like-and-kind homes with similar square footage with similar condition in a similar location and you make calculated assumption that if they sold for a certain price that your similar property should too.

Penny -Either strategy can work for you, but the underlying problem here is Risk Management.Risk refers to the uncertainty of the cash flows and the assumptions you use in your investment strategy, so as long as you can manage the underlying risks of interest-only loans you should be fine.There are 3 risk factors that I see here:  1) Underlying property values, 2) Risk of interest rates, and 3) Risk of your ability to refinance the properties. 

You could make some assumptions on how frequently the other company's other fees would be charged and see how it worked out on an annual basis.  

You came on here asking for opinions, and now you are arguing against all of those opinions.You are making a lot of assumptions about what the HOA (and I hate HOAs, by the way) will and will not do, without really a lot of information to support those assumptions.Let me be frank, and tell you how an HOA board member is likely to see you."

I'm guessing the OP is making a lot of assumptions that what he can do in his market can be easily (and cheaply) replicated elsewhere.  

I work under the assumption that you mean total.  

Everything else came out fine.Do my assumptions look okay or am I missing something, considering that this is a townhome? 

I am inclined to think it may be your ARV assumption.
