If you are looking to just calculate profitability, set how much profit you want to make then:ARV - Purchase Costs - Holding Costs - Selling Costs - Desired Profit - Rehab Budget (including contingency) = Maximum Allowable OfferIF you cannot calculate those numbers, a spreadsheet isn't going to help you. 

My partner and I keep an excel spreadsheet of rent, our purchases, utilities, taxes, insurance, and money spent on contractors.

The one's I prefer handle everything in house, from purchasing the home, renovating it, renting it, then selling to an investor then managing for them on the back end.

I am a rookie investor and have not purchased a property yet.Thank you in advance.

A seller can not sign away his rights in a purchase or any other document.

Purchase price: $115 Cash invested: $17,000 This is my first fix and flip.

There are no restrictions preventing out-of-state investors from purchasing rental properties in Texas—these investors enjoy the same opportunities as Texas residents.Additionally, the financing restrictions you mentioned don’t align with reality.

In my area specifically most investment type property listings are properties that were purchased 1 to 2 years ago.

Purchase price: $375,000 Cash invested: $30,000 This was a 2 unit that I purchased in 2016 for $375K.

When the home was purchased, it was conventional loan and the basement had tenants.
