I do not have to much cash for a down payment but was thinking of doing a HELOC on one of the rentals to get more cash and go the BRRRR method.

He collects cash down payment and finances the rest.

How many mortgage lenders have you spoken with to get qualified and discuss allowable down payment options?

Wanting to evict them are a tenant is late for a week or waiting months of non-payment to start the eviction process.

If you were me, just starting out, first property ever, would you use this money to find a BRRRR deal or use this money for possibly 2-3 properties for down payments? 

She put a portion of the down payment (15K)...and of course there is a little equity...

However, our tenant turned out to be problematic—late payments, issues that led to an eviction, and additional repair costs before we could relist the property for sale.Now, after months of making mortgage payments out of pocket, we finally have an offer.

I would need to put $45,000 down upfront, with a monthly payment of about $650.

Would it be wise to use a HELOC on our current residence to use for a down payment on a new property You can make $ investing anywhere.

do not use a line of credit for a down payment.
