To be honest, all of them work, it just depends.What I have been learning over the years for me is I prefer 2-4 unit properties.

I haven't worked with anyone since we prefer co-hosting but know oodles and oodles of hosts that do it.

Inspections may cost more upfront, but they can save you from significant headaches and unexpected expenses down the road.Negotiate Hard: Use inspection findings as leverage.If the HVAC is near the end of its life, negotiate a credit for its replacement.If the cast iron plumbing is deteriorating and needs replacement, ask for a credit as well.Sellers often prefer negotiating credits over doing the work themselves.To give you an example: I was once under contract for an old house priced at $170,000.

My attorney says he prefers it when there is a business reason for the state of the LLC, and he said either your home state or where the property is located is suitable.A much bigger topic is whether or not having an LLC is a good strategy given your personal situation. 

However, in the long run, I love the "buy a house a year" strategy (as a primary, for preferred financing) and just keep moving (pending that your spouse is on board with this of course, if you have one).

Assuming it will be Single Member LLC (you as a member/manager), it will come back on your schedule E anyway, so only thing you loose is $800 in california and bit more of paperwork but that preps you for future.Note - this is a very high level advise and mostly a personal preference. 

Then yes, maybe you can a couple hundred a month on your $50k.

When I sold my properties, the price did not increase much (though there was still a slight profit, couple with the rental I had over the years and currency gain (bought when USD was low and sold when USD was high).

Yes, preferably in mountains.

Mold needs warmth & humidity, and preferably darkness.
