Zig's quote is foundational principle of my real estate investing, but I'm thinking of upgrading now.What do you think?

.$100 per sq. ft quoted without any upgrades sounds high.

He used it to drive his clients around town and the IRS allowed him to deduct the cost of the upgrades.3.A couple hired a babysitter so they could do charitable work.

Another plus, is that the tenant would have a big investment in the way of equipment, and tenant upgrades meaning less likely to walk away from their lease.

(owner dumping becuase expensive upgrades needed)Is something changing that could affect the value?

No upgrades after the fact.I would only entertain some upgrades after a year if they've been good tenants and are renewing for another year.

The small, or basic, level is the property without any upgrades.

It may not be the case in all localities, but most counties will take an upgrade on the mobile home "eyesore" even if they don't want more mobile homes in their area.

I mean, sure - I hope my property values climb and I can sell off some of my properties to upgrade to bigger/better things.

Here are my parameters:$100k cash to invest into CRE.Monthly cash flow I can allocate to this investment: $3000-$4000Buy power: Excellent credit, and minimal obligations currently (no mortgage as of right now)Targets: Would entertain retail space, medical office space, or multi-family.Willing to: Make upgrades and improvements to the property (family has access to trades/contractors), and I'm willing to self-manage as long as it's in Houston area.Goals: Positive monthly cash flow >$500/month, an investment/location that will appreciate over time, already leased would be a plus.So with the above parameters what would you suggest?
