You need to do renovations, improve the property, and drive up rents.

The price was low in 2014, today that same price is riduculously low, and the buyers in 2014 improved the property tremendously and recently re-sold for $230,000, good for them! 

Many investors make the mistake of over-improving their purchases in Class C/D areas, which when damaged by Class C/D S8 tenants - costs them thousands.Another fallacy of S8 investing is that the S8 Caseworker will keep the S8 tenant inline by threatening to take their voucher away.- The reality is this depends on each individual caseworker.

You will benefit from better rates and lower cost lumber now, so that will help make up for some of the added carry and perhaps the market conditions have even improved? 

But we already get deductions for maintenance, repairs, and improvements.

Buying quality assets with a larger amount down, making improvements, and paying off debt could get you there relatively quickly. 

Our team transformed the property by investing $35,000 in targeted renovations, focusing on modernizing its appearance and improving functionality.

Marketing and home improvement activities may count as well, provided they are directly tied to property operations.2.Time Spent by OthersThis ties back to keeping a logbook.

If I understand correctly you'd be purchasing the land, and improving it and splitting it into the appropriate "buildable lots". 

@Richard NguyenHere are some of the downsides of putting real estate into a self directed IRA or 401k.No tax deductions: You can’t claim deductions for property taxes, mortgage interest, depreciation, repairs, improvements and other property-related expenses.Property expenses: All expenses, repairs, and maintenance costs must be paid with IRA or 401k funds, and you must pay others to do repairs and manage the property.
