For example starting payroll, filling W-9 for independent contractors, tax rules, bookkeeping e.t.c?

Maybe the current rules aren't the best (they assume that people with more money are more sophisticated, which may or may not be true).

It sounds like you might be referring too one of the three available replacement property identification rules which allows you to identify any number of properties as long as the combined value of the identified properties does not exceed 200%. 

If I'm right about paying no tax on a land contract for an amount exactly what I paid plus all improvements, then I'd rather do that than take the hit on the sale.  

If you're not willing to cramp your style enough to plex hack, let's see if you can do small things every day to improve yourself.Rates on the cards and car don't matter.

Hi there, I'm unsure of the tax rules in USA but I'm familiar with them in Canada and I'm assuming they are similar with respect to depreciation (CCA in Canada).

Mobiles in a community are subject to lot lease rates and community rules that you are responsible for similar to a condo except governed by the community owner.

If you cannot afford to pay a property manager, and you don't want to quit your Job, then you should consider paying down some loans to improve cash flow rather than buying more units.

My company offers a loan based on ARV (after repair value); so the appraisal estimates what the market value will be after repairs or other improvements are completed.

Hi @Brad Chatman @Eric Michaels make some worthy points to look into.I invest where I live in SE Chicago and me living here is the only reason - to improve where I live and it's easier for me to deal with.
