I will definitely use an agent for the next couple buys, and indefinitely for sales, but I'm looking to get more independent on the buy side.

They have a much better metal bracket than the usual cheap blinds for a couple of bucks more.

Hello BiggerPockets,My name is Jason and I am brand new here to BiggerPockets.

Here are the key data points:Park info  Located in Alabama61 lots25 owner occupied homes18 park owned homes (14 currently rented; 4 currently being repaired and should be rented soon)18 vacant lotsAvg lot rent - $160 (unknown what the market rate is but it doesn't sound like there has been a rent increase in at least a year, maybe more)Avg POH rent - $400Expense ratio - seller claims 26% but I'm estimating 35% for the lots and 50% for the POH'sCity water - individually meteredSeptic - good condition (allegedly); a couple were pumped last year, none this year (no lagoon thank heavens)Seller claims gross income $130k, expenses $30k, and NOI $100kI calculated gross income of ~$135k, expenses of $60k (55% on POH and 35% on lot rentals), and NOI of $75kOther infoMom & pop seller, but park is listed with a brokerPark has been on the market for > 3 years (recent price reduction)Greater metro area stats look goodPopulation = 115kMedian home price = $105kUnemployment < 8%Household income > $40kHousing vacancy ~ 15%Closest Walmart is 7 miles awayFreeway is 1.5 miles awayNumbersMy valuation is coming out about $80k-$100k under the seller's asking priceWith conventional financing I'd be hoping for a purchase price of $500k, $100k down @ 6% over 20 years (not sure if this is plausible or not)Assuming that financing, I'm expecting net cash flow of $40k (after debt service)Upside potential is in raising rent and filling the 18 vacant lotsFollowing the same assumptions above, raising rent $50 (if the market supports it) would change NOI to ~$90k and net cash flow of just over $50kFilling the vacant lots could potentially increase gross rent up to somewhere between $150k-$200k, depending on what the appropriate occupancy rate is for the areaWithout verifying any of the above information (haven't offered anything yet so there's a lot of DD left to do), the deal seems to make sense. 

What I did in that scenario was I took out the student loan, and used a fraction of the money that I would have used to pay for tuition to buy a couple notes.

After spending a whole couple of days reading through various forum posts, I'm still not clear on how people who invest in 100s of investment properties, deal with their taxes.My biggest question is this: Suppose, I refinance my existing primary residence or an investment property and end up using cash-out to buy another investment property.

The spreads have to be there as well even if you check a couple times a year, its going to cut into your earnings a bit..... 

What brand is most reliable and durable?  

@Justin Bock - couple questions . . . 

I wanted to cover a couple aspects and see if anyone can help tie up loose ends.
