My investing plan is to acquire a Small Multi-Family unit using an FHA loan, move into one of the units and subsequently acquire more SMHs before trading up for a small apartment complex.

In each subsequent year, the seller will pay capital gains tax on 50% of the principal he received from you, plus income tax on any interest you pay him.So, in your case, the seller will pay tax on the gain included in the down payment you make in 2020, which will be due in April 2021. 

He was willing to generously and freely share his knowledge about note investing with a newbie, as have so many others subsequently (thank you all).

You should be able to do this for about $750.Now, for subsequent LLCs, you can take those docs and change the LLC name, then file them yourself with the state for $70.How many LLCs do you need? 

As far as your premium questions if the lien is bid down to 0% or at a premium at auction, the lien will not generate interest for you until you pay the 1st Quarter's subsequent taxes. depending on the dollar amount, you will generate 8% or 18% (lien < $1500, 8%: lien >$1500, 18%) as long as the lien is redeemed within 5 years (may vary from town to town and county to county) the premium is given back.

This makes it harder to get a loan, although not impossible, from a conventional lender.2) My broker also told me that even though I can now get up to 10 loans from a conventional lender, I'd have to wait some amount of time between subsequent loans.

Finally, I understand the seller has subsequently apologized for any offense caused by the curt language you referenced in one recent email, and that they have committed to completing your property expeditiously in accordance with the contract terms.

I have a tenant turn over list that we use on each tenant turnover that hopefully eliminates issues with the subsequent tenant and protects the unit. - in my market we had the most stringent Covid eviction moratorium in the country.  

There was a subsequent law which mitigated the insurance premiums but that is only in the short term.  

They charge per item so it can get expensive, but you can lower the cost quite a bit by working with one of their account reps.For the particular issue of loan balances, you can also do it yourself by using the original loan amount and original loan terms typically found on the deed of trust, and any subsequent notices that may impact it or provide more information - like a foreclosure notice.
