Hello @Alex Silang,It depends on your goal.

Real estate : you could become good at advertising and marketing or simply asking people you know if they want to buy or sell: Any realtor will give you $1k to $5k depending on the price to get that buyer  or seller.

It also depends on how much money you have and how you use it.

Depending on where the property is situated and the "local market conditions" I have them rented out as either long term, mid-term or short term.

I've had smooth loans close with Kiavi and I've had rough ones, same with Roc.When Loans start to be troublesome:1) The borrowing entity docs are a mess2) The appraisal numbers are lower than expected3) Messy background reports4) Loans happening in an environment where market/rate fluctuating unpredictably 5) Your loan officer and their team are poor at their job6) Title issues that depend on county docs, that can be slow and painfulThere's more but it's Friday and I'm tired....

Also, you will have additional occupancy tax depending whether you are in the city limits or not.

Rents should be a modest $1500 per side, depending on the time of year I’m able to get it on market.

It may even be higher than 5% depending on the area. 

I would still do due diligence such as whole property inspection, lead inspection (depending on when the property was built), appraisal, etc. 

I think you can go as high as 15% but it's cutting into your margins and depends if you are a GC yourself or not. 150k is close to a million or more.
