If there are pieces that are already falling apart, then your best choice is to put vinyl on top.

That's how I visualize the moving pieces. 

Start with the most important piece...a location and a realtor.

My ultimate goal is to buy a piece of land and develop a 25-30 multi-unit apartment complex.I have read books, attending the seminars, paid for the classes, watch the YouTube video, google things that didn’t understand which have brought me to this point of budding career as a real estate investor.As of right I looking for a few things:1) A mentor.

I don't think this is the most efficient way and there might be another person with the same name owning a piece of property.

My group bought 2 good size deals last year in this smokin' hot seller's market (full disclosure- we did underwriting on about 500 deals though) and there's no reason why you can't get a piece of the action. 

In some cases that is an all-in-one solution and in others that is several different pieces working together.  

Cost segregation looks at the $400k of the building and picks out pieces that qualify for a different treatment.

Mortgage interest deduction is only a piece of the pie, look at the whole deal from an IRR perspective over time. 

@Upen Patel You made me curious when you say that a HML is a mortgage irrespective of whether it has been recorded are you saying in the sense that it’s a loan on a piece of property and therefore a mortgage or is there another method of legally recording a mortgage?
