Finding a partner or mentor can cost money on your first few deals, hiring a guru costs money out of pocket. 

In my timber days I looked at one 8 acre property out of felton that had over 2 million board feet of redwood on it.. at 1000 a thousand that's 2 million in timber... but the greenies we could never get a cutting permit.. and had to decamp to Oregon.. to put it in perspective in the commercial douglas fir timber grounds you need close to 80 acres to get the same MBF yield.. there are legal lots of record up virtually every drainage coming out of santa cruz and going up the coast towards half moon bay and along skyline..

(my bf can do most construction type work, but there are situations where he may not be available so I'd have to do it myself or hire someone?

It's highly dependent on who you hire I have discovered, I have rehabbed  with 'side-job' workers for a fraction of the price.

Can you hire a part time person to work in the cleaning business while you establish the 2 years of income?

You may want to consider hiring a good architect  and contractor with experience with this type of work. 

Hiring a contractor is also a good idea, however your inspector (if they are good) can give you rough estimates or tell you directly if its something to walk away from.  

Then use that to hire another corporate property manager.

I was little skeptical at first because I've seen quite a few gurus trying to sell systems for virtual wholesaling to automate or make a simple formula for rehabbing estimates, or sell you some software.

Cheaper than hiring a lawyer and cheaper than most of the other gurus out there.
