With $30k cash you can buy two single family homes or a duplex out of state with a property management company and tenant in place. 

Or do you think Single family flip is better ?

2024 is 6 years awayI plan to spend the next 6-12 months learning and studying dealsI estimate that in order to replace ~$130,000 of gross annual income I will need to have that same total of net cash flow from my properties by that time (I currently only own two single family houses)If I make the assumption that the deals that I find/buy return $500 per month of net cash flow then I will need a total of 22 properties to equal $132,000 per year (22 * $500 = $11,000/mo. * 12mos = $132,000/yr)The $500 per unit estimate is not a per door estimate, rather a per unit estimate.

My single most important criteria whether purchasing single family or a mobile home park:Is my cash on cash return.

And I would put single occupancy only per room in the contract as well... and then add an admendum of house rules. since verbal/oral contract is not really held high in court... if you can't sign the contract write away then use technology such as text message or emails or even voicemails. 

I'll be targeting single-family homes with good school ratings that I can purchase at a discount for one reason or another.

I am currently able to save around $2500/month and am wondering what some of your opinions are as far as a route to go for starting off in this area and market.I am either looking to find a duplex and house hack it, or start with finding a good single family deal and live in it for a year while building equity and then move to a duplex and house hack it.

We are now buying a single family for ourselves near by.

I worked alongside professionals as a "helper" With pretty much no construction experience, they put me on the dirty grunt work, cleaning rat poop, removing the old toilets, scrubbing down baseboards, etc. but as I was doing that, I was watching every single thing they did, and pestered them with tons of questions on how to do things and different techniques.

Not a single issue to date and saved a lot of money.
