For you, the buyer, the cap rate allows you to compare investments to each other.  

Hi Vadim, If you have a real estate agent on your team, they can search the area near you for closed leases on properties comparable to yours, in age/condition/square footage.

I will run a comparable market analysis for you. 

He was a principal in the creation of the SAFE Act while at HUD, and in many manufactured home related issues at the CFPB until his retirement.Regulatory law is both complex and complicated when compared to other forms of law because in order to understand how it will play out, you first have to understand what the original intent of the law was when passed, rather than just what exists in writing.

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.
