Buy a property in decent condition, do some spit and polish upgrades (paint, flooring, etc.), hire and vet a Prop Manager, and use a regular 30 year mortgage to buy a property on market. 

Underwood nailed it. 

@Chris Seveney kind of nailed it but I have an example I'd like to give you.I started building homes in 2016.

@Dave Foster has nailed it very well.

We targeted C class properties that needed some work to get started.  3-4 years ago (when we were buying heavily) this took on average about $30,000 to close on a deal, and then we would spend maybe $5,000 polishing up the place (new carpet or tile), and maybe some new paint.Today it’s probably tougher to find that deal.  

@Danny Liu Hit the nail on the head! 

@Anthony C Valera Anthony hit the nail on the head with the SF. 

@Sanat Bhandari nailed it but I will add this: Earlier this year we were looking to scoop up a small multi-family in Miami using an FHA (this wasn't our first FHA) and in networking with a lot of the local investors many of them simply got their mail sent to the property and had an agreement with the tenant in case anyone came knocking on the door.

We need more info, to really nail it down

@Melissa Nash Nailed it!
