MAYBE if it's materials only.....Good luck and trust your numbers, not thiers!

Renovation...you control this:  how much you do, what grade of materials, what gets done now versus later.So how long does this take:  an hour after walking it. 

Keep doing it as long as you live.Bonus material for everyone - It is possible to convert a property from investment to primary. 

Complete the course, study the material (watch Prep Agent on YouTube), and take the state and national exams when you turn 18.

I believe what has driven me to focus on working with investors, has a lot to do with my flexibility and ability to perform most of the things you can do in a home, and eye for design and detail.

I didn't notice until I had driven away and when I went back to the title company, everyone else had left the office and the clueless secretary said "Oh, they changed what they wanted to pay because the buyers said they didn't want to pay that much." 

I could be wrong (also not a licensed expert) but I think using a management company does make a difference as it would be difficult to prove material participation if a management company is the one doing all the work.Just another reason to self manage!

This is also just local impact, now add to that the federal impact of interest rates at basically zero, forced shut downs of building materials suppliers, and adding trillions of dollars to the money supply.

Most systems now a days use a copper radiator that has fins connected to allow heat transfer and air flow.Steel radiators are known to leach out additional material into the water that is circulating. 

We purchased this home (and the one next door) as a fix and hold residential property to be used as a short-term rental that I materially manage.
