There are also owners that buy at $30,000 home that is dilapidated, in the worst part of town, and not in rentable condition to anyone that has a job or just standards in general.I suppose there is the chance that you were done wrong by 5 property management companies, and had a run of horrible tenants, but I would wager a guess you got what you paid for. 

Typically, when I work with RE investors, we'd make a preliminary legal plan to ensure that both the legal and business goals align before creating any sort of entity set-up.

Was your tenant offered a preliminary inspection during the two weeks prior move-out as required by law?

And sometimes banks are the ones who mislead such a home buyer, by issuing pre-approvals and approvals to sign a contract, but then back out when more sophisticated underwriters spot an issue (in buyer's income, credit score, DTI, property value and etc.) that loan officers who gave preliminary approvals didn't want to see.

Doing so, with preliminary numbers, would reduce our monthly income by a $150 or so since we would have a mortgage on the cash house plus the new house.  

Based on my calculations and preliminary research, I have found that the Bay Area offers good returns from developing land, although acquiring level land and obtaining permits can be challenging.I have a few questions:1) Is it recommended to purchase a complete house plan from online sources like ePlans or similar websites and then customize the architectural design before submitting it to the municipality?

(other than having cash/equivalent, preliminary title report, and the appropriate deed ready to go 'on hand')

In some municipalities they require both a preliminary plan and a final plan, effectively making you go through the approval cycle TWICE. 

Send direct from main platform.1) Time of booking2) 5 days before: Preliminary check-in/out info and check-in time reminder  3) Day before departure at 3 pm, with checkout instructions/time reiteratedIf a host is getting more questions than that-- the listing or instructions are not clear.

And even then, if you do not do a preliminary title search, you could get stuck with liens and mortgages you weren’t expecting.
