It’s easy to switch it up or add to it or replace it if parts or the whole thing gets damaged.

I recommend establishing a reserve fund for major turnover expenses, capital repairs like a roof replacement, etc.

Otherwise, yes you have to either excavate and repair and replace or run a pipe burst through the line, which is usually as expensive as excavating. 

I was determined and wanted something that I could sustain for the long term for my family's livelihood and control the effort I put in and the results I got from that effort.I specialize in sourcing properties for fix and flip investors nationwide (wholesaling, but with real-world experience and closed profitable deals for myself and my investor partners) with a roadmap to acquire rental properties as finances permit.A lot of our deals are currently coming through organic search as I have a background in substantial traffic generation through search engine optimization and organic means.

I requested money from the guest for replacement and contacted Airbnb in the meantime, and the guest left me a bad review because I requested them to pay for it. 

Labor/material are going to be different and need to factor that in4) new roof, new HVAC, new water heater, ac panel, replacing plumbing to PVCThese are very variable, if you are getting this from a licensed guy to do it and unlicensed.. is it a big shop or a local shop doing it, is the GC doing it they will put some money on the top so it will be more money5) framing (creating new bedrooms or baths)I would get all these quoted from a good couple of licensed guys and unlicensed to know your numbers to cents

Some questions I have.1) Do you make enough from your houses that you can not only replace your income but also make enough that you can continue investing in real estate?

If separate, do they both need to be replaced?

They usually do not have these figured out, I mean sure, everyone wants to 'make money', or ' own 10 properties in 3 years', or (my favorite) 'replace their W2 job in 5 years'.....but they have not thought any further than those basic (and misguided) goals.

For example; you could target high earner W2 IT engineers.
