So for the DIT issue you can look into DSCR loans as they are based on the property and its ability to generate enough rental income to cover the mortgage, taxes, insurance, etc., as opposed to your personal income and your ability to afford it.
For the money issue you can look at getting a private investor to partner with to provide said funds. The thing with that you will want to be careful of though is making sure your lender is ok with the funds not being your own and being borrowed. That is where you will likely find bring in a money partner the hardest if purchasing as a turn key rental.
If you are looking to use the BRRRR method, then you will still want to make sure that the lender is ok with the funds from someone else but you will also have the exit strategy of refinancing and paying the lender of as well as partner off that funded the down payment.
So I think it will come down to the lenders that will allow secondary financing as well as what your strategy is.
