How is NY so different that the tried and true valuation methods don't work there???

I know it might be tough to get new MHs into this park and I agree the quality of the mobile homes are probably well below average.

For a bit more rehab, could turn it into a 2/1 with an attached 1/1, and even reno the garage for another 1/1, with good rents over the winter months. 2) SCRAPE AND BUILD: On the other hand, I approached a high quality local developer who proposes we do a JV- I bring the land, he brings his reputation, expertise and oversight of the development and construction, and clients- he has several would-be buyers looking to build in the area.

Any other suggestions or methods i could use to get my first SFH investment property for a Buy and hold?

For family activities, quality of life, etc - I prefer Greenville. 

If your rentals are not primary residence quality for you then sell one or two and 1031 into something that would make a good residence.  

For instance buying a 50k rental in the mid west may be small change to some so they say what the heck I don't need to see it I will shop just like I shop at Amazon and buy it basically on line.Others will spend much time and money checking it out.. flying there and making certain its for them.I do think one way to dial for dollars is to contact those that bundle it up for you IE turn key type companies.. and I think a lot of time can be saved by talking with a few reputable PM's in a given market.. they will for sure be able to tell you were the management intense areas are.. and one's that are easier for them to manage. ( Ie code for quality of tenant) 

Maybe hold for several years and upgrade as I grow.Any thoughts from other investors that may have started in the lower priced houses and then worked up to nicer/better quality properties?

I haven't seen anywhere that discusses this method. 

However, there are alternative methods to this.
