i recently closed into a property which I bought from another investor who got it through a tax deed sale.

Going into a potential deal, I look at the track record of appreciation (sales comps) in the immediate area, not the general area, and based solely on properties that are within 10% higher/lower in sq ftg than the property I'm looking at.I have a goal of a specific number ()in dollars, NOT percentages) that I need to achieve in appreciation. 

This means they must provide credible evidence to support their claims and comply with all substantiation and record-keeping requirements mandated by the tax code.Despite the taxpayers' testimony that the RV served as a boat sales office and provided nighttime security, they failed to produce any records or documentation to substantiate these claims.

Make sure that the property's value is in line with market trends and comparable sales in the area.

If your property is worth less than that, it could be a reason to make the sale.

As noted above, a non-QM loan product such as DSCR  could be suitable if you don't have a W2 track record.

Go to the sale and see what they sell for.   

Taxes are calculated on the annual sale installment gain. 

Essentially, I’m buying out my partners and transferring the lots to my own LLC.1.Do I need a purchase and sale agreement for this type of transaction?
