We've been educating ourselves on creative financing and Subto and would like to know if there are recommended professionals in the DFW/ Texas area who are experts on structuring a creative deal who can essentially advise us and take care of the process for us. 

Like other comments suggest, you may be able to secure long term debt sooner but if for whatever reason that is not the case feel free to connect with me.

Hello BP STR experts, If I buy land first for constructing/manufacturing home, can I then claim bonus depreciation for such a constructed/manufactured home and use that calculated depreciation amount to offset my W2? 

You could make up an assignment, not record it, and send it to the person to hold to secure the loan, but if they recorded it, you would be screwed.

I'm not an expert but I would be cautious.

I have settled on a $300 security deposit.

Either that or hire an expert to tell you what it means.

I will hire out to another expert to handle other aspects of our finances to make sure those are on the right track.

You can collect the money in many ways, I have tenants pay using secure ACH transfers using apartments.comI would declare this income because later on you may need the documented income to qualify for loans etc.

The tenant threatens to get lawyers, my concern is their safety, but I can’t get any justification to make improvements to the property for security.
