Usually in the year following your purchase, the property appraiser will reevaluate the house based on the new sales price.  

Have you had an appraisal done recently, or do you have comps to estimate the property's market value?

Do to an anomaly pertaining to the appraisal district, the total value of the two lots was divided equally between the lots instead of allocated by market value.  

Unfortunately due to the property values, the cash proceeds will be disproportionately impacted by transactional costs associated with the financing (doc prep, appraisal, recording etc.) which will also hurt the available proceeds compared to the same LTV financing of higher value real estate that can better absorb these transactional costs. 

@Brenden Stadelman in general legit lenders do not ask for maney up front other than for an appraisal.

@Richard Benjamin Wilhite, A great place to start would be the county appraiser records. 

They also know about real estate so less likely to charge you extra fees to get an appraisal or BPO because they can estimate the value themselves.

I own the property next to this and it appraised at 105K most recently. 

The real estate appraised at $3.5M. 

I think I have about 450-600k equity depending on how well the properties appraise.
