Instead of doing a 3-yr bullet you may consider making the note adjustable at 1% escalation annually past year 3.

They told me they only adjust every few months, it has been over 7 months since I made several requests.  

Difference is, because I’m wholesaling, for rehabs, can I get the price close enough for the end buyer, so that I do not have to go back to the seller for a price adjustment?

As a former adjuster and fellow Dallas investor, I’ve seen this often.

The $80K from the HELOC used for personal debt won’t affect taxes but must be repaid upon sale if tied to the property.To minimize taxes, keep detailed records of your remodel expenses and selling costs to adjust your taxable gain.

If they are adjusting the amount they can lend because the margins are too thin or telling you the deal metrics are not checking out it is likely due to the expected earnings not being sufficient. 

Obviously, the at least 42 input variables can be adjusted to your own risk tolerance, but this is far easier/quicker than to re-create the entire input.You can find the link on my profile page.

But you also have to apply your level of risk aversion or risk adjusted return.  

Strategic timing matters, especially with multi-state portfolios.Real Example:Investment property sale in 2019Federal noticed unreported gainTwo states involvedTimed response to fall after state deadlinesResult: Only federal adjustment appliedInvestors: What's been your experience handling tax notices across multiple states?

I am inclined to believe this is the chief complaint and they either have another option or underestimated their ability to adjust to a rental.
