This means that the rent compared to PITI is reasonable.You can help the seller sell on terms and save some money for the seller, then you can take that house and rent it out for positive cash flow or lease it with an optionSay you have a $100,000 house with $95,000 against it, seller has to leave soon, market rent is $800, PITI payment is $600You can make 3% by putting together a lease with an option or a lease purchaseSteps1.

@Matt McCourryFirst off, 1-4 units are considered residential, not multifamily/multiunit and are priced based upon comparative sales and not on income.  

I researched what some comps in the area are paying for a comparable house worth 70,000, and the yearly taxes were around 1,000$, nearly a 30-40% increase!!

Your cashflow won't be as great (early on) but you are saving in interest and compared to a 30 yr fixed loan, your mortgage will be paid in half the time.

Welcome @Sanzhar ZikirovI would say not to get discouraged and don't compare your progress to those here, as you are working with a very different set of circumstances to those of us in North America. 

This is great news for you on two fronts:1) it should increase comparable rents in the area. 

The labor for a 200 amp compared to a 100 amp is the same. the only thing different is the ratings of the materials, they are heavier for the higher amperage. 

@Matt R.The prices in CA are so extreme compared to other areas, like here in Rochester. 

When I discovered the tax, appreciation, and rate of return benefits of real estate as compared to stocks, bonds, or p2p lending, I decided an addiction to REI would be in my best interest as an investor.

Is the place next to you comparable?
