Definitely recommend the seller financed buydown as if you refinance whatever the remaining balance from the buydown is can be used to pay down the principal balance of your loan. 

I have about 150k equity in my home and have $215k balance on my mortgage.

You lease should state a interest fee for unpaid balances.

Wages will also go up, and we will see a better labor/capital balance as we negotiate end-stage capitalism.  

And, having ready access to capital allowed us to scale more quickly.  2) Because the compensation is so balanced, it makes passive investing much more attractive.  

Sure, it’s easy to get nervous about over-leveraging... no one wants to feel like they’re juggling flaming torches while balancing on a high wire.

Without knowing the balance on the first, I wouldn’t touch it at at the auction.

I consider that a liability,  don't want it on my balance sheet and if I were out of funds I would sit on the sidelines before entertaining that deal.

If I bring on an agent who does not join, I get billed for it and all my agents memberships gets suspended if the balance is past due.  

If the deposit does not cover the charges, then you should consider whether you want to pursue collecting the unpaid balance or write it off.You did the right thing, and the tenant's behavior proves you were right.
