Can I use Buildium for bookkeeping including tracking all transactions per LLC including mortgages and can it produce detailed reports at tax time?

Once that is completed, then run the credit for those that meet the first round of criteria.You can double check but I have not heard you have to prioritize a Section 8 tenant, you just can't reject them because of source of income.

Look into syndications, but vet the operators first, that is passive income as an LP, not owning rental properties.

The benefit to them is that they receive income over time, and the benefit to you is that you don’t need to pursue bank lending.  

I have saved enough for a down payment for a house and have a steady income coming in.

There would still be the transaction (tax) effects if using it to purchase the propertyA non-gimmick situation however would be borrowing against your BTC in dollars so that you don't have to sell anything and see the tax/transaction effects. 

Thanks to the Cost Segregation Study, the property investors were able to reclassify the property components and accelerate their depreciation for a total of $356,000 in the first year.The use of the accelerated depreciation strategy helps real estate investors to reduce the tax liability immediately which therefore increases their bottom line due to the offsetting of income.

Currently, I find myself in the 37% tax bracket due to W2 income and I'm eager to explore avenues to shelter taxes through real estate investments.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

You're looking in the right place because TX is going to appreciate much quicker over time but the cash flow won't be as much since the taxes are higher.
