@Ed Gonzalez it’s best to put the least amount down provided the investment cash-flows with all expenses accounted for including Capex AND provided you have a healthy reserve account of at least 6 months worth of PITI payments but preferably a reserve account of $10k to ensure you can keep your property.

I do have a SEP that is pretty healthy for someone 32 years old.

You would then owe 160K on a 300K property still a healthy ratio.  

I'd look for deals in the suburbs South of there and be aware of clay soil and foundation issues.

I have a rental property with a healthy amount of equity in it.

I am 20 years old and in a healthy position, no bills and nice savings to start with.

-Costs of street development and utility extensions (public water and septic)-Approval process for subdividing, what should I make contract contingent on to protect myself (approvals, soil tests, stormwater etc)-Is there a form of financing people generally use?

Also, this loan has limitations, which are that the property must be located in specific "healthy neighborhood- target blocks" .

He recently started his small business for deliveries (i.e. mulch, soil,  sand, gravel, caliche, etc.) and lawn service. 

On the flip side, I could tear down the screen porch, which was a poorly-done addition anyway and have the tank removed.The cost of the abandonment is $2500 + soil testing which may be up to $4,000 out of pocket costs for a state-mandated site test.
