can i invest in a property with a down payment?

Your PITI Payment would be $1,298.82 per month.

You can always start off by house hacking meaning you live in one UNIT or ROOM and renting out the other vacant units/rooms to offset your monthly mortgage payment.

This includes allowing the seller to foreclose on myself and my team should we ever fall behind in payments, which we will not.

My question is do I need to use all of the equity towards the down payment of the property, to avoid capital gains tax? 

You can no longer make decisions regarding the house, you no longer own it, but you have to keep making the payment if the person you sold to doesn't. 

The seed money started as an SFR that I put $30K (hard earned savings) as a down payment.

Saving yourself 2-3% on your down payments can be a nice benefit.

Details below...We need a FAST cash-out loan product that requires only the personal guarantee of my business partner (60% ownership) to be used for: completing the remaining rehab and getting the 1st house rent ready, paying off revolving credit accounts to get her credit score up, and funding the other projects we have in the works.To help bring you up to speed on what's transpired over the 11 weeks we've been in business...We started our business on Dec 1, 2023, leveraged our "then" good credit/high w2 incomes to bootstrap the startup, assembled a rehab team, and are now about 2 weeks out from the completion of our 1st rehabbed property.We've closed on 3 properties, all owned free/clear, and have paid for renovations with personal funds/credit.My credit score was 810, but is now 592, due to excessive debt but 100% on-time payments, therefore can't personally guarantee a loan.My business partner's score is currently in the 700s, but likely wont be for long, due to her revolving credit % continuously increasing, as we push towards the completion of the first rehab utilizing her remaining credit on her CCs.Recently, I started researching the underwriting timeline for DSCR loans.
