Allan, I generally never respond to blogs but happened to read yours and had to... I would first start off by saying it seems that the old adage might fit you "you have enough information to hurt yourself".
I am a real estate investor myself and look literally at thousands of properties every week throughout Florida. The only way to answer your question is to know what the FMV (Fair Market Value) is for that home, that area, that neighborhood, that sq ft, for that year of home, etc. I would say Ms. Lynn from Coral Springs had the best advice. You need an expert to answer some questions for you on today's value for that home.
I appreciate that you did a public search for information on the Lis Pendens and it is good to know how to do that but that is just a tiny piece of information and is basically useless for someone who is not an investor.
As a real estate investor the more I know the better offer I can make. You should know what the SALES trends are for that neighborhood over the last 3, 6, and 12 months You should know how many homes are for sale in that neighborhood (careful Realtors generally use only their bible, MLS and Tulia doesn't necessarily have the most updated info..)
We purchase many properties in Central Florida but not familiar with the Conway market. We work with many Realtors and have come to know some of the best. If you want free advice get an Expert Realtor they will save you 10â€™s of thousands on your purchase.
