For example, this investor that I met recently said not to buy properties at tax auction for 100+ different reasons.

I read on Lee Arnold system . com that joining the inner circle gives access to up to 100% financing on residential loans including Property Purchase Price + Closing Costs + Rehab Costs if that amount is 65% of the after repair value (ARV) as determined by a third party appraiser.  

A reasonably good source is AVVO.com by zip code and expertise.  

Do you have a price range that you'd be targeting for your first property?

They have a good selection of quality rugs for reasonable prices.

Is one of these institutions superior for any reason? 

Credit score- the higher the best. 760-780+ generally gets best pricing for investment property loans with most lenders.

Purchase price: $185,000 Cash invested: $5,000 Sale price: $220,000 Occupied by my in-laws.

@Jack Cottrelli get nervous when new investors buy random properties out of state.this is below the median price in KC, so i am assuming it may be in a more challenging neighborhood.  

The reason is because the companies that back these assets, and some others, have a 1:1 between their tokens and the USD (I'm unfamiliar if EURS, THKD, and stables of other fiat offer 1:1).A possible scenario would be that you offer the seller to pay in a stable coin, like mentioned above.
