Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

Hi BP community - I'm an investor with 3 SFHs in the Nashville area looking to acquire my first small multifamily property (2-4 units).I'm trying to determine the best approach for the 25% downpayment, comparing using cash that is currently sitting in a high yield savings account to funds from a HELOC on one of my properties.

You are prepared to walk away from a deal.Not going to give you the answer (maybe if you were Army or Air Force) LOL, but here is the approach. 

I would keep detailed records of my deals to include photos that I could use later when I am approaching a potential funding partner.

I think the safest approach would be offering the package at a certain price and excluding the alcohol.

approach it the same way you would interviewing a business partner because that is what you will be. 

I think this approach ensures that every aspect of the chosen location is carefully scrutinized, helping investors make informed decisions.

A more intrusive approach would be to Google the owner name and see if you can find relatives and skip trace and call them.

Financing Options: With 20K, how should I approach financing?

I appreciate the structured approach you've outlined for getting started in real estate investing.
