I've come across a few interesting ones, but they are built in the 1950's, 40's and 30's.I know some of the things that I need to consider in these older properties when deciding what price to offer is potentially upgrading the plumbing, electrical, insulation, etc.So I wanted to get some feedback on how to get a sense on how to estimate the costs to repair plumbing and electrical?

How new are the roof, HVAC, Electrical that you only budgeted 5% for these?

You can go after them in small claims court, don't waste the energy. 

Cabinets, floors, plumbing, electrical etc.

Income of $200 and you have an electric bill higher than that.

Much cheaper when there isn't electrical work or stuff that requires permits.

Getting started before anyone else lets you work when energy is high, and you are not distracted by calls, emails, kids, friends, colleagues etc.

I make sure that the roofs are in good condition, the siding, replace windows if they are not energy-efficient, etc.

I think you should have an overall vacancy rate that is much lower than 10%2) Electricity, Water, Sewer should all be removed because the Tenant will be paying for those utilities3) Garbage should be included in the tax bill instead of outside expense4) Property management can be brought down to $60/single family home

Some of the the things I would look for:Are the floors levelCracks in foundationRoof qualityCracked roof joist or wall studsWeird electrical junction boxesFunky plumbing... pvc pushed into cast iron pipes... cracks in piping
