may signal something off, be it with the property (like something outside or nearby that is an eyesore), the price, or even the rental market in that area or neighborhood being weak. 

Don't try to fudge the numbers to make the deal work because it will sink you when the real numbers happen.It sounds like you are asking; do you do a weak or bad deal because you can pull it off easily.

I have  been investing since end of 2015- although in fewer platforms than yourself- (Pol, RM, RS, FtF and Acquire. )- On the one hand multiple platforms gives one access to diverse opportunities and there is always something available, but on the other hand the portfolio also begins to become a bit unwieldy to manage.As an investor with experience in so many different platforms it would be interesting to hear your opinion as to comparing their strengths/weakness, advantages/disadvantages.

My weakness at the moment is knowing how to estimate repairs.

While some national trends, like interest rates can effect all markets, most markets have factors that keep them strong for some reasons and some have factors that make them go weak while others stay strong. 

WEAK!

I closed because I thought it should not be a big problem, they are on month to month lease, so we will give 1 month notice.We were renting for the last 13 years, never had any issue with any landlord, never miss or delayed any  payment, I still have good relation with all landlords.There is a signed lease of month to month from previous owner, that I got as part of closing.I could slap them with 1 month notice without any talk to them on day one only ,I knew that verbal talk is nothing in terms of legality,I just talked to them frequently because I wanted to be nice landlord, but for some people "Nice" mean "weak".

Account Closed - That's a big question, and the answer depends on your goals, your strengths/weaknesses, your capital, your risk tolerance, your market, and I'm sure several other factors I can't think of right now.

There is a lot of money to be made if things go well, but you may need some sleeping pills to get you through the night when things go sideways and millions of dollars are on the line......Developing land is not for weak minded amateurs for sure,  and there are lots of safer, easier ways to make money.  

I would caution though, its not for the weak of heart especially in Austin.
