Special needs, recovery?

Q3) If it's a loan from our parents that we are paying off, who holds the title to the home?

However, he wants to be off the loan within two years of purchase.

Although in the next few years I'll be starting a family and will want a single family home, if I put in the work of finding off market / on market multifamily deal the medium term rents could be insane. 

something to note i plan on doing private loans and house flipping down the road also.

Broad Street to the north, Demorest Road to the west, Sullivant Avenue to the south, and Hague to the east.

I completely get why condo associations need to levy special assessments and increase monthly fees, and specifically in this case to comply with the recently passed laws in Florida.My objection is to buying these FL condos as possible rental properties.Buying condos for investment is already a risky proposition.

ADUs in SRH areas typically get valuations far below the hands off ADU addition cost.  

And what is the trade off bypassing? 

Call a septic company and they will come with their truck, dig down so they can pop the top off, pump it out, and inspect it for you.If you've had contractors in the house, I wouldn't be surprised that things that shouldn't have been flushed were flushed.
