So the question becomes based on their individual and personal tax situation what is the estimated tax burden they'd save? 

Taxes/Insurance- depends a lot on where you are located.The homes themselves- POH or TOH? 

It’s definitely smart to evaluate the tax and cost implications of your funding options.

Tax-Free Exchanges: While 1031 exchanges aren't available to SDIRAs, the tax deferral within the account means you can sell property and reinvest proceeds into new opportunities without immediate tax consequences.

If so, there are no transfer taxes due. 

The sellers you are dealing with in these situations don't deal with prorating Taxes, or any other kind of prorations, that is what an escrow agent does. 

Some people only want 10-20% of their outstanding lines/debt balances available while the other 80-90% to be in fixed rate notes.

I know how to use the basic features of QBO, as I do my own expense tracking, but my Bookkeeper is needed for the more complex entries (Loans, capital balances, reconciliation, data entry from PM monthly statements.)I spend almost 8k per year in QBO and Bookkeeping costs (Not including my accountant or tax prep.)

Current rent…,,,,Alternate rent……..If you bought monthly PI, ins, prop tax, maintenance, etc………Your cashflow available on top of your current rent. 

Being a real estate professional allows you to treat the income as non-passive, allowing higher high income tax payers to pay less in taxes.
