The property is unused most of the year. 

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.

as others have stated, if a RE agent does not believe they can sell the property, find a different agent that believes they can sell the property.  

I imagine you also ensure the amount you're lending is less than the ARV of the property.

They cannot continue a lawsuit on your behalf if you have not authorized it.I would send them a short demand:"You have five business days to stop the lawsuit and turn over all documents, funds, and anything else pertaining to my property.

if its a true condo you only buying the airspace.. so any defects in constructin the HOA has to pay to fix.. so the ceiling work should be on them. 

As an owner you're allowed to manage your own properties.  

There are many advantages that small multi-family properties have over single family properties in my opinion.

When I purchased my property, I had read all the exciting developments in the works...indoor waterpark, shops, new hotels, restaurants, etc., but was severely disappointed when I went recently with my family. 

Create rooms within existing square footage, look into ADU properties, etc.
