I think you should call a HVAC/ Mechanical person as soon as possible.

Whoever records the lien first has Senior/First Lien status all other liens are Junior to the First/Senior lien.There are some Super Liens that jump in line for some states like HOA, Municipality and Tax Liens for example.Hope this helps.Jeff VIn Oregon a properly filed materialman lien is a super lien.. not sure I know any other state that is the case.. so contractors who are on the ball and go through the proper steps to have a valid mechanics pre lien .. if it becomes a lien it jumps in front and the lender will cure.. ask me how I know  LOL 

We pay a mechanic to work on our cars.

Hi @Yuriy Skripnichenko,  It has always been mine and my partners rule to leave instructions for anything mechanical we provide, such as smoke detectors, microwave, etc., in the units for the tenants.  

Hello Biggerpockets,I live in San Diego and I'm a project manager in mechanical construction and looking to find a way to get involved and get started in real estate.

In addition there were several other smaller issues including structural and aging mechanical.

But even that can be tricky.Dehumidifiers and ACs are fundamentally the same thing - a mechanical refrigeration unit. 

The HOA has to pursue previous owners separately and they have a mechanism to foreclose for delinquent HOA dues.

The HOA Declaration of Trust it states the following:  "No unit owner shall make any addition, alteration, or improvement in or to his unit or any portion of the common areas and facilities to which he has the exclusive use, which may affect the appearance, structure, or mechanical systems of the condominium, or which is otherwise restricted by the Master Deed without the prior written consent thereto of the Trustees.

it's a distressed property so of course there are some things wrong.it's freddie mac REO, way past the owner occupant period which ended in january 2018. it was originally listed at 50k dec 2017. went under contract in july at 42k, now it came back at 38k. but looking on redfin it was on and off the market since 2012.its in a neighborhood where houses are selling between 70k - 135k. in fact the 135k looks just like this one and its on the same street. on the inside it's pretty nice, seems like just paint and flooring. might need new mechanicals etc and some mold in basement. so as a newbie i'm thinking, what am i missing?
