I think the benefit of a mini split system over a central are the energy efficiency the offer, the individual control over zone cooling/heating, simpler maintenance, quite operation.In the end it comes down to what makes sense in your situation, but I will say that there is a lot of fear mongering among a lot of HVAC companies to push people to either central systems or if they do mini splits, then into the higher priced systems. 

Second is the ongoing rental stream.You will always "numerically" make more money developing/renting versus buying/renting. 

I am a 21-year-old individual excited to commence my investing journey along with my partner in the St-Louis real estate market.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = $2300/$1875 = 1.23DSCR lenders generally let you vest either individually or as an LLC.

I believe that this approach minimizes downside by exploring the numerous currently for sale opportunities with assumable mortgages.

In the meantime I read every book I could find on commercial real estate; attended every commercial real estate meeting in the Houston area, and spoke to numerous commercial brokers.

In my city's codes and ordinances it states that one of the common rental property violations is having "over four unrelated individuals residing in a dwelling unit" would the dwelling unit be considered the entire house or just the part contained in the lease (aka the room)?

I've had people ask me this on numerous occasions and I have refused.

It also doesn't seem to recognize a quoted string versus the individual words in a search query.

each area has nice features but they are different in valuation >the ranking's in Neighborhood scout don't give any scale.neighborhoodscout provides percentages in addition to the numeric comparison score I find more useful because it is not as easy to recognize if a certain percentage is good or bad over a period of time.
