It's been great - the property is 100% paid off and the house is worth 300-340k generating approx $2300/mo (that's after utilities/management fees etc.)I'm considering selling the property to buy 3 more within the same price range in the same market. 

You're marking the equities to most recent returns, the reality is a real estate investment to live in is a guaranteed rate of return and serves utility. 

Utility improvements.

all materials, all labor costs to others, Not you, utilities, interest payments, permits, licenses, auto/truck expenses, tools needed are all deductable. 

To determine the correct treatment, consider the RV's permanence, utility connections, and business use.This post does not create a CPA-Client relationship.

Usually MTR comes fully furnished with utilities included, so you pay for the convenience.if the area has traveling nurses, other professionals that come for a few months for work they normally pay more, in certain cases the employer pays the rent not familiar with that particular market,  but worth looking into it.

We decided I’d utilize an FHA loan to buy my first property.

@Marc Robinson some may be more adventurous than me but with septic and well I would walk awayI prefer TOH of course but with $300 lot rent and 19 occupied, utilities included in rent I would pay $400-450k for this

I mean myself and any bank would need more details, but if you utilize that large sum as a downpayment and have a small mortgage, wouldn't you easily qualify for the debt to income?

@Will Almand this sounds like a very useful case for cost segregation especially if you can utilize the depreciation expenses against your income.
