You then put $50K in to it, and sell it for $200.

He started selling off properties and investing in more syndications, then eventually started his own syndications.Why invest in individual homes that require your time and energy, or that causes stress?

Unfortunately there is literally no street parking in the area and the vacant land next door and corner store are not willing to lease or sell parking spots. 

Jane wants to sell to me and escape of the headache of land-lording .

., I am not sure if the customary relationship is the same in Canada as in the US, but when you get into commercial listing in the US, typically the buyer is self represented and the broker is representing the seller.That being said, are you looking to buy or sell property?  

I can tell you that the best leads are properties that were on the market, did not sell and you need to go after those leads.

And although I didn't intend to sell as much initially, I ended up really liking selling a lot more than I thought. 

So I came to peace with selling.  

so most people will have to be as leveraged as possible to scale (at the beginning). as in, keep your LTV high and focus on buying 'as much' ($$) RE as possible. this is if you're doing a pretty run of the mill REI strategy like buy and hold. i came across an interesting guideline once: if you could sell today and net 7x+ your annual true net cashflow, you should cash-out/refi, or sell/1031. think of it this way: if your portfolio in a year is worth 1m market value, and you owe 600k, and have a lender that will do a portfolio loan at 80% ltv, you could cashout refi and get 200k to play with (minus closing costs). when you compare the now-lower cashflow from the existing portfolio (higher LTV & maybe different rate), to what you can do with 200k cash, THAT'S where it gets fun. maybe you lose 1k/mo in cashflow on the original portfolio (literally just made up a number, idk), but you can gain 2500/mo in cashflow with that 200k.. then doing the cashout/refi earned you a net increase in your monthly profit of 1500/mo, plus you're getting debt paydown and appreciation on "more" real estate, probably getting bigger tax benefits, etc.

I think Installments sound strange and like a lot of problems waiting to happen, not to mention the risk of not being able to sell and then being out the carry costs, etc.
