I asked flat out if it can be replaced.

Two flats seem to all net negative, though they are the only ones possible from a 5% DP perspective... even including a garden apartment.Breaking even, were you wouldn't need to pay, would be a success. 

I've been investing since 2006, sold all my SFR and solely investing in commercial e.g. warehouse/industrial.I handle acquisitions and leasing for a flat fee.

I can't speak to what other Self-Directed IRA companies charge, but Directed IRA charges a flat rate $295 annual account fee regardless of how many assets or what the account value is. 

It's not just flat billbacks since at $50 (or whatever number), that's $50 if you don't use a drop vs $50 for leaving every faucet running 24/7. 

For example, we have a rental with a flat roof. 

Just make sure you bake that into your numbers.

The roof is flat which concerns me if we get a bad winter, though I've had no issues so far.- The property should cash flow by 300 or more.

However, I fear it is a half baked solution until they address the arbitrary limitation on the number of accredited investors in Reg D offerings.Progress is progress, I suppose.

You can also ask for a flat fee.
