Hi Kristin,It really depends on what the after repair value of the house is if you intend to wholesale the deal.A typical formula (some adjustments are made for market strength or location) is that a cash buyer is going to want to spend no more than 70% of ARV minus the fix up costs.

And they all have a different formula.

A common formula used to day is:MAO = ARV X.65 minus repairs.

I am currently logging them on excel, but I am not familiar with the commands and formulas to operate excel efficiently, or if it can even do what I need it to do.

You should be buying every property using the standard formula which is 65-70% of the ARV (after repaired value), less repairs, less your wholesale fee.

Not sure if the market in Florida is the same, but man, your formula is worth taking a look at!

Take Dale Osborn's formula and subtract the projected costs of repairs needed to get max offer amount.

It confuses the ones who are learning the formula.

The formula many rehabbers like to use is 60% (or less) x ARV (After Repair Value) Minus Repairs = the max you should pay for the property.

On the old mobilehomeuniversity.com site they used to have a formula based on the following: 1 months lot rent X number of occupied spaces X 60. + 1 months lot rent X number of vacant spaces X 30.
