Again, my goal here is to see if I can develop a "top down" analysis whereby I can establish some reasonably accurate and verifiable method to derive a target market.

The budget is derived from the common area maintenance and other cost items the association will be paying for such as insurance and its cost to operate.

The 80% is derived from some magic capacity to refinance at 80% LTV.

Adversely, fluctuations in net worth can be derived from playing with the assets and liabilities a part from actually delivering a return.

It's hard to give you a definitive answer without any numbers, which are ultimately derived from local conditions..

I really think QR codes (or some derivative of a scanned code) will be big.

Paul -- that's rather uncanny, the one on 7678 Canova Way is also 75k, 1255 sq ft, and built in 1977, in the same zip code.The ROI of 17% is derived -- in shorthand -- as follows: 8% net yield + (8% yield - 5% borrowing rate) * 3 = 17%.

you will want to see that land value gets considered to your advantage in this (a comparable similar in construction and building size but with a larger lot will have more value in the land, so the dollar per sq ft for the structure should be a bit less).I would also check the county records to see if any other appeals are being won or lost, and try to contact those property owners to see how their experience went.One other thing to consider is that there are many firms out there who offer to appeal taxes for property owners promising a reduction (from which they derive a percentage commission based on reduction as their compensation), or charge no fee if no reduction happens.

The income derived from my properties allow me to live better on the money I have in retirement plus allows an opportunity for wealth to grow for my 3 daughters twins 8 years old and one 7.

This has been asked and answered here a number of times.First, what a state does or does not mandate as a maximum number to sell manufactured homes derives from legislation and secondary legislation that regulates and restrains the ability to sell manufactured homes.
