Yes, you'll need to convince (or at least verify) that the seller will take hard money.And the lender will likely provide a 6-12 month loan, with the stipulation that you intend to resell the property, not rent it or move into it.

You can almost get 6 units for the same out of pocket investment buying separately as you can buying the 6 unit, potentially slightly less cash flow with a better rate and less stipulations.

Most lenders don’t consider manufactured or mobile homes real property and there are lots of requirements and stipulations a buyer has to meet to qualify for a mortgage.  

Having two insurers refuse to pay as stipulated in my policy may seem limited to you...it's very real to me.

Some commercial leases have weird stipulations. 

We include a clause in our contract stipulating that closing is contingent upon tenants vacating. 

My friend said even if this person could be struggling and be late a couple of times a year or may not make 1 month rent once a year, since she is a long term tenant per her past and paid her rent without fail every month, and is motivated to make the new rental situation work for her financially, long term, if she stays 5 years, although occasionally could struggle a bit, I still will do better than most other tenant choices (frequent turn over, etc.)My rent is still covered by my past tenant at the moment even though the property is vacant as the Lease has stipulations for that the past tenant has honored faithfully.

Forget to stipulate utilities in the lease.

The lease stipulates that each of them are responsible for the full rent amount.One tenant has just moved out and the remaining one is asking for the security codes on the doors to be changed.I’m not sure where to go with this.

For FHA 203K (rehab loan), all work will need to be done by a licensed contractor per stipulation of loan type for major renovations.
