My wife and I are building a triplex close to the beach in a popular vacation spot in Florida. 

@Cody Burke in order to analyze the deal we need purchase price, $ amount of rehab, after repair value, and estimated monthly rent once property is rehabbed.

I am more interested in what you consider when you analyze the street and neighborhood where a residential property is located.

However, one taught I have been contemplating, is a lease-option; wherein, I would deposit US$9,000 as option fee, and make monthly payments of US$5000 per month for 60 months, then refinance balance of US$600,000 from the bank or private lender after analyzing the long-term earning potential as a villa.

I'm going to great lengths to roll out 95% LTV $1.5m o/o SFR, I'm also constantly analyzing fulfillment/funding times, etc, would I be doing all of that if I were the only game in town? 

If you don't have all the blanks completed it is hard to analyze the numbers.  

I love house hacking, looking forward to analyzing some of the informed responses on this thread!

Are there any popular and free design software out there??

I have analyzed 10 deals a day, and have viewed every single house in the market with my zip code 39056. 

I have been spending the last few months extensively watching podcasts, reading books, the BP forums, and practicing analyzing properties.
