You don't know if they even received the mail much less read it.

You have to register with the State and pay your sales and use taxes monthly based on the rent  you received the month before.

I bougt lease forms from BiggerPockets and I received them in PDF and Microsoft Word formats.

What would be the maximum HELOC I could receive?

@David RobertsWhat @Ashish Acharya said is of course correct, but is also highly complicated.Considering that the entire deal started and ended (for you, I mean) within 2018, and no partnership returns have been filed, you may consider cutting corners and treating the deal as 100% your partner's for tax purposes, especially since the eventual sale will be reported under his SSN.On your end, you will report the difference between the total payout you received from him and your total investment as your taxable income.

I’ve invested into 4 properties in Memphis for 30k and received an ROI of 42%.

For background, there is some termite damage on it,that should be taken care of prior to close, as well as some other minor fixes to the roof, basement, etc.I received a quote for the building for an After Cost Value (ACV) policy, which was about 40% of the Replacement Cost policy.  

Utilities are in, phase one of the roads, curbs, gutters and water retention has been completed as well.I have received approval from the municipality to build the project as duplexes that will optimize cash flow and raise the number of finished units to approximately 300.I owe 1.25M and need 1.05M to finish the roads, curbs, gutters, and water retention.The first lien(1.25M) is overdue and was intended only as a bridge.The finished value of the subdivision would be 3.4M -4.5M as finished lots, depending on the comparables the appraiser uses.I have also found a lender that will lend to take the first out, but his points are high, it's not hard to get very expensive in points on a loan size like this.I am outside the Phoenix and Tucson markets in a smaller but rapidly growing area.

I asked the question in my last post regarding out of state investing and received a tremendous response with some very helpful feedback - thank you everyone!

And don't trust any pro forma statements they make, get the actual paperwork for rents received, operating expenses, etc.
